Pull up revision 1.14 (requested by he in ticket #719):
Make the SSLOTS, MSLOTS and JSLOTS tunable (redefineable).
Bump the default values for these to the values used by FreeBSD,
and also adjust ti_init_rx_ring_jumbo() to use the same constant
that FreeBSD uses.  Yes, this consumes more kernel memory.
The effect of this is that you can use jumbo frames in a back-to-back
setup with TCP windows up to about 250KB and get ~930Mbit/s throughput,
while we were earlier limited to around 3-400Mbit/s, and trying to push
above that mark by widening the TCP window caused
  ti0: jumbo buffer allocation failed
messages to be logged and a corresponding stall in the traffic.
