- Updated TOE support in the kernel.

- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
  These are available as t3_tom and t4_tom modules that augment cxgb(4)
  and cxgbe(4) respectively.  The cxgb/cxgbe drivers continue to work as
  usual with or without these extra features.

- iWARP driver for Terminator 3 ASIC (kernel verbs).  T4 iWARP in the
  works and will follow soon.

Build-tested with make universe.

30s overview
============
What interfaces support TCP offload?  Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE

Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe

Which connections are offloaded?  Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe
