*** 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.

Start patching up the kernel so that a network driver always has
the opportunity to handle an ioctl before generic ifioctl handling
occurs.  This will ease extending the kernel and sharing of code
between drivers.

First steps:  Make the signature of ifioctl_common() match struct
ifinet->if_ioctl.  Convert SIOCSIFCAP and SIOCSIFMTU to the new
ifioctl() regime, throughout the kernel.

Miscellaneous ath(4) and net80211 updates and bug-fixes coming from
sam@ and various open source repositories:

ath(4):

        Ignore "phantom" beacon misses: should stabilize connections
        to access points (no more ceaseless link-UP/DOWN indications).
        Also, re-synchronize beacon timer using the TSF in the
        first beacon received after joining a BSS---this should
        also help suppress spurious beacon misses.  I am hopeful
        that this will help ath(4) lossage reported by perry@ and
        smb@.

        Add new configuration through sysctl.

        Use a shorter calibration interval until IQ calibration
        finishes.

        Report antenna noise through radiotap.

        Rudiments of Radar Detection / Dynamic Frequency Selection.

        Update to HAL version 0.9.16.13.

        Update open sources for changes to the HAL API.

        Add HALs for additional architectures: add big-endian ELF
        HALs for sparc64 and for PowerPC.  Also add a Alpha HAL.
        These new HALs are untested under NetBSD.

ath(4) + net80211:

        Make the multicast transmit rate configurable by ioctl.

        Miscellaneous bug fixes.

Clarify/fix handling of the current channel:
o add ic_curchan and use it uniformly for specifying the current
  channel instead of overloading ic->ic_bss->ni_chan (or in some
  drivers ic_ibss_chan)
o add ieee80211_scanparams structure to encapsulate scanning-related
  state captured for rx frames
o move rx beacon+probe response frame handling into separate routines
o change beacon+probe response handling to treat the scan table
  more like a scan cache--look for an existing entry before adding
  a new one; this combined with ic_curchan use corrects handling of
  stations that were previously found at a different channel
o move adhoc neighbor discovery by beacon+probe response frames to

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

Split crypto tx+rx key indices and add a key index -> node mapping table:

Crypto changes:
o change driver/net80211 key_alloc api to return tx+rx key indices; a
  driver can leave the rx key index set to IEEE80211_KEYIX_NONE or set
  it to be the same as the tx key index (the former disables use of
  the key index in building the keyix->node mapping table and is the
  default setup for naive drivers by null_key_alloc)
o add cs_max_keyid to crypto state to specify the max h/w key index a
  driver will return; this is used to allocate the key index mapping
  table and to bounds check table loookups
o while here introduce ieee80211_keyix (finally) for the type of a h/w
  key index
o change crypto notifiers for rx failures to pass the rx key index up
  as appropriate (michael failure, replay, etc.)

Node table changes:
o optionally allocate a h/w key index to node mapping table for the
  station table using the max key index setting supplied by drivers
  (note the scan table does not get a map)
o defer node table allocation to lateattach so the driver has a chance
  to set the max key id to size the key index map
o while here also defer the aid bitmap allocation
o add new ieee80211_find_rxnode_withkey api to find a sta/node entry
  on frame receive with an optional h/w key index to use in checking
  mapping table; also updates the map if it does a hash lookup and the
  found node has a rx key index set in the unicast key; note this work
  is separated from the old ieee80211_find_rxnode call so drivers do
  not need to be aware of the new mechanism
o move some node table manipulation under the node table lock to close
  a race on node delete
o add ieee80211_node_delucastkey to do the dirty work of deleting
  unicast key state for a node (deletes any key and handles key map
  references)

Ath driver:
o nuke private sc_keyixmap mechansim in favor of net80211 support
o update key alloc api

These changes close several race conditions for the ath driver operating
in ap mode.  Other drivers should see no change.  Station mode operation
for ath no longer uses the key index map but performance tests show no
noticeable change and this will be fixed when the scan table is eliminated
with the new scanning support.

Cleanup beacon/listen interval handling:
o separate configured beacon interval from listen interval; this

o bounds check the beacon interval received in probe response and
  beacon frames and drop frames with bogus settings; not clear
  if we should instead clamp the value as any alteration would
  result in mismatched sta+ap configuration and probably be more
  confusing (don't want to log to the console but perhaps ok with
  rate limiting)

Fix handling of frames sent prior to a station being authorized
when operating in ap mode.  Previously we allocated a node from the
station table, sent the frame (using the node), then released the
reference that "held the frame in the table".  But while the frame
was in flight the node might be reclaimed which could lead to
problems.  The solution is to add an ieee80211_tmp_node routine
that crafts a node that does exist in a table and so isn't ever
reclaimed; it exists only so long as the associated frame is in flight.
