sys: Drop redundant NULL check before m_freem(9)

m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c

Compile-tested on amd64/ALL.

Suggested by knakahara@

Audit unload/unmap v.s. free against DMA buffer for sys/dev/pci;
make sure that bus_dmamap_unload(9) [or bus_dmamap_destroy(9)] or
bus_dmamem_unmap(9) are preceding to freeing DMA buffer, if it is
loaded or mapped, respectively.

This is mandatory for some archs. See, e.g.:

- Change the definition and usage of TI_HOSTADDR() to allow for 64-bit
  DMA addresses.  Modeled after similar usage in the bge(4) driver (the
  chips supported by bge(4) are descendants of those supported by ti(4)).
- Use the 64-bit PCI DMA tag if available, otherwise we're allocating (and

Adopt <net/if_stats.h>.

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

 Don't automatically set ec_capenable's ETHERCAP_VLAN_HWTAGGING bit in

Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input

The benefits of the change are:
- We can reduce codes
- We can provide the same behavior between drivers
  - Where/When if_ipackets is counted up
  - Note that some drivers still update packet statistics in their own
    way (periodical update)
- Moved bpf_mtap run in softint
  - This makes it easy to MP-ify bpf

Proposed on tech-kern and tech-net

Apply deferred if_start framework

if_schedule_deferred_start checks if the if_snd queue contains packets,

Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

Sync with HEAD

Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

in the thread at tech-kern@ and tech-net@:

Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client.  This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached.  However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff.  ... and I'm not going to ponder the depths of unload
here.

Update haad-dm branch to haad-dm-base2.

*** Summary ***

When a link-layer address changes (e.g., ifconfig ex0 link
02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor
Advertisement to update the network-/link-layer address bindings
on our LAN peers.

Refuse a change of ethernet address to the address 00:00:00:00:00:00
or to any multicast/broadcast address.  (Thanks matt@.)

Reorder ifnet ioctl operations so that driver ioctls may inherit
the functions of their "class"---ether_ioctl(), fddi_ioctl(), et
cetera---and the class ioctls may inherit from the generic ioctl,
ifioctl_common(), but both driver- and class-ioctls may override
the generic behavior.  Make network drivers share more code.

Distinguish a "factory" link-layer address from others for the
purposes of both protecting that address from deletion and computing
EUI64.

Return consistent, appropriate error codes from network drivers.

Improve readability.  KNF.

*** Details ***

In if_attach(), always initialize the interface ioctl routine,
ifnet->if_ioctl, if the driver has not already initialized it.
Delete if_ioctl == NULL tests everywhere else, because it cannot
happen.

In the ioctl routines of network interfaces, inherit common ioctl
behaviors by calling either ifioctl_common() or whichever ioctl
routine is appropriate for the class of interface---e.g., ether_ioctl()
for ethernets.

Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR.  In
the user->kernel interface, SIOCSIFADDR's argument was an ifreq,
but on the protocol->ifnet interface, SIOCSIFADDR's argument was
an ifaddr.  That was confusing, and it would work against me as I
make it possible for a network interface to overload most ioctls.
On the protocol->ifnet interface, replace SIOCSIFADDR with
SIOCINITIFADDR.  In ifioctl(), return EPERM if userland tries to
invoke SIOCINITIFADDR.

In ifioctl(), give the interface the first shot at handling most
interface ioctls, and give the protocol the second shot, instead
of the other way around. Finally, let compatibility code (COMPAT_OSOCK)
take a shot.

Pull device initialization out of switch statements under
SIOCINITIFADDR.  For example, pull ..._init() out of any switch
statement that looks like this:

        switch (...->sa_family) {
        case ...:
                ..._init();
                ...
                break;
        ...
        default:
                ..._init();
                ...
                break;
        }

Rewrite many if-else clauses that handle all permutations of IFF_UP
and IFF_RUNNING to use a switch statement,

        switch (x & (IFF_UP|IFF_RUNNING)) {
        case 0:
                ...
                break;
        case IFF_RUNNING:
                ...
                break;
        case IFF_UP:
                ...
                break;
        case IFF_UP|IFF_RUNNING:
                ...
                break;
        }

unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and
#ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4).

In ipw(4), remove an if_set_sadl() call that is out of place.

In nfe(4), reuse the jumbo MTU logic in ether_ioctl().

Let ethernets register a callback for setting h/w state such as
promiscuous mode and the multicast filter in accord with a change
in the if_flags: ether_set_ifflags_cb() registers a callback that
returns ENETRESET if the caller should reset the ethernet by calling
if_init(), 0 on success, != 0 on failure.  Pull common code from
ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(),
and register if_flags callbacks for those drivers.

Return ENOTTY instead of EINVAL for inappropriate ioctls.  In
zyd(4), use ENXIO instead of ENOTTY to indicate that the device is
not any longer attached.

Add to if_set_sadl() a boolean 'factory' argument that indicates
whether a link-layer address was assigned by the factory or some
other source.  In a comment, recommend using the factory address
for generating an EUI64, and update in6_get_hw_ifid() to prefer a
factory address to any other link-layer address.

Add a routing message, RTM_LLINFO_UPD, that tells protocols to
update the binding of network-layer addresses to link-layer addresses.
Implement this message in IPv4 and IPv6 by sending a gratuitous
ARP or a neighbor advertisement, respectively.  Generate RTM_LLINFO_UPD
messages on a change of an interface's link-layer address.

In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address
that is broadcast/multicast or equal to 00:00:00:00:00:00.

Make ether_ioctl() call ifioctl_common() to handle ioctls that it
does not understand.

In gif(4), initialize if_softc and use it, instead of assuming that
the gif_softc and ifp overlap.

Let ifioctl_common() handle SIOCGIFADDR.

Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels
that certain invariants on a struct route are satisfied.

In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit
about the ioctls that we do not allow on an agr(4) member interface.

bzero -> memset.  Delete unnecessary casts to void *.  Use
sockaddr_in_init() and sockaddr_in6_init().  Compare pointers with
NULL instead of "testing truth".  Replace some instances of (type
*)0 with NULL.  Change some K&R prototypes to ANSI C, and join
lines.

cur_rx->ti_vlan_tag holds the 802.1q VLAN tag and the 802.1p priority.
Trimm the priority, as the upper layers won't do it and will drop the packet
if priority is not 0.
While there, print the revision in the "unsupported chip revision" printf.

Add missing binding of VLAN tag to received packet.

Change ext_size to a size_t, and update the signature of ext_free.

SIMPLEQ rototill:
- implement SIMPLEQ_REMOVE(head, elm, type, field).  whilst it's O(n),
  this mirrors the functionality of SLIST_REMOVE() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
  this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups

Change the semantics of mbuf external storage "ext_free" routines
so that they're more useful for arbitrary types of external storage:

* Add an "mbuf *" argument to (*ext_free)().  If non-NULL, (*ext_free)()
  is expected to free the mbuf itself.  This allows (*ext_free)() to use
  the mbuf for bookkeeping (e.g. deferring the work to a helper thread).
  If the "mbuf *" argument is NULL, we are assumed to be in a context
  which is safe for performing the destructor operation *now*.
* Adjust MEXTREMOVE() and MFREE() routines for above change.
* Update "ade" and "ti" drivers for new semantics.

Use MEXTADD() rather than open-coding it.

Use BUS_DMA_READ and BUS_DMA_WRITE in some obvious places.

bzero -> memset

bcopy -> memcpy, strcpy

For product names that include the media in the name, don't bother
saying "Gigabit".

IFM_1000_TX -> IFM_1000_T, as (breifly) discussed on tech-net.

Sync the Tx descriptors pre- and post- on the Tigon 2.

When we're done setting up the General Information Block, sync it.
Sync the NIC-maintained stats structure as appropriate, as well.

Use macros (like those in every other network driver I have written)
to compute the offset of a structure in the DMA'd control data, and
the DMA address of that structure.

Split the tx-end-of-frame routine into Tigon 1 and Tigon 2 verions,
for the same reason we split the tx encap routine.

Split the transmit encap routine into two versions: one for the Tigon 1
and another for the Tigon 2.  This eliminates a conditional in the
loop around the DMA segments, and will make further cleanup easier.

Move the `ti_tx_ring_nic' pointer out of the ring-data structure
and into the softc.  Garbage-collect the `ti_cmd_ring' pointer,
since bus_space is properly used to access the command ring.

When a transmit is complete, sync (and unload!!) the DMA map used
for the packet.  When setting up a packet for transmit, sync the
DMA map being used.

Move the Tigon/Tigon2 firmware, version 12.4.13+wpaul, to a
more appropriate location.

Correct spelling of media in the product names.

When setting/changing an address, no need to call ti_init() if the interface
is already up.
Especially this allow netatalk to start properly on a ti interface.

receive, not recieve

Set TI_OPMODE_1_DMA_ACTIVE only if hardware assisted checksum isn't used
(FreeBSD does it this way). My Tigon II works with hardware assisted checksum
now.

In ti_init2(), use a simpler, more obvious, and correct MTU
calculation to give the firmware.

Replace a bunch of home-grown Ethernet related constants with
ones defined in <net/if_ether.h>

Implement support for IP/TCP/UDP checksum offloading provided by
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

Pull up revision 1.12, 1.15 via patch (requested by bouyer):
  For the ti driver, add hardware 802.1Q support, update firmware
  to 12.4.13+wpaul, and support the Netgear GA620T copper gigabit card,
  and the Alteon ACEnic 100baseSX and 1000baseT gigabit cards. Various
  small changes from FreeBSD.

Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Pull up FreeBSD changes:
1.39:
Have if_ti stop "hiding" the softc pointer in the buffer region. Rather,
use the available void * passed to the free routine and pass the softc
pointer through there.
1.33:
Add support for the Netgear GA620T copper gigabit card.
1.32:
Tweak probe message so that 1000baseSX and 1000baseT cards are
explicitly identified.
1.31:
Update the Tigon driver to support 1000baseTX gigE over copper AceNIC
cards. This basically involves switching to the 12.4.13 firmware, plus
a couple of minor tweaks to the driver.

NetBSD changes:
get rid of ti_inuse, the mbuf ref counting code should call ti_free() when
needed.
Use hardware 802.1q support.

Move bpfattach()/bpfdetach() calls into ether_ifattach()/ether_ifdetach().

NBPG -> PAGE_SIZE

- use jumbo rx if mtu is too big to fit in one mbuf, not when larger than
  ETHERMTU.
- add support for ETHERCAP_VLAN_MTU.

Move the check for "promisc + unicast + not for us" into ether_input(),
and change Ethernet drivers to always pass all received frames to
ether_input() (with a few exceptions, which are documented in the
code).

Pullup revision 1.10 (approved by thorpej).

  Fix multicast filters. Patch from Keijiro Ehara.

Add calls to ether_addmulti and ether_delmulti. This code looks a bit
different than other drivers due to the way ti_setmulti manages the
filters. Patch from Keijiro Ehara.

use new generic bootverbose instead of local definition

Pull up revision 1.3 (requested by he):
  Make the ti(4) driver compile again after the wi(4) related
  pullups of if_media.h changed IFM_1000_FX to IFM_1000_SX.

Apply patch (requested by bouyer):
  Fix compile error.

Pull up revisions 1.6-1.7 (via patch, requested by bouyer):
  Fix bug which could result in a panic.  Add a shutdown hook to
  stop the board to avoid memory corruption on reboot.  Use bus_space
  for TIGON 2 chips, so that they will work even if we can't map
  the memory space linearly (e.g. on alpha).

Remove register declarations.

Fix botched merge in previous.

- remove leftovers of FreeBSD code in #if 0/#endif
- fix a bug in ti_encap() where a NULL pointer could be used if we run out
  of tx descriptors (return ENOMEM instead, and let the caller assert OACTIVE)
- sync boot messages with NetBSD's pci standart (print ti_name and irq
  line)
- add a shutdown hook to stop the board, so that the board will not DMA at
  random places while we're rebooting
- convert all but TIGON 1 transmit descriptors to use bus_space
  (this last one isn't trivial to get rigth and I don't have the hardware to
  test)
- If we can't map the mem space linar, retry to map it nolinear. Punt if
  we couldn't map the mem space linear and we found a Tigon 1 chip.

With these changes a Tigon 2 board (netgear BA620 at last) can be used in
my DS20.

Set ifp->if_baudrate as appropriate.

Remember to account for ETHER_ALIGN when setting the maxmimum packet
length for mini receive ring. The max length was MHLEN, however the mbufs
are actually shortened to MHLEN - ETHER_ALIGN to force payload alignment.

Pull up revision 1.1+patch (new, requested by drochner):

  from FreeBSD.

file if_ti.c was added on branch netbsd-1-4 on 1999-10-05 22:08:51 +0000

quick 'n dirty port of FreeBSD's Alteon Gigabit Ethernet driver.

-IPv6
-clean up jumbo buffer allocation - NetBSD provides an opaque argument
 to the free function, thus doesn't need the hack done here
-deal correctly with the mapping of the shared memory
