- Copy stable/10 (r259064) to releng/10.0 as part of the 10.0-RELEASE cycle. - Update __FreeBSD_version [1] - Set branch name to -RC1
[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so start releng/10.0 at '100' so the branch is started with a value ending in zero.

- 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

- update firmware to 5.0 - add support for T3C - add DDP support (zero-copy receive) - fix TOE transmit of large requests - fix shutdown so that sockets don't remain in CLOSING state indefinitely - register listeners when an interface is brought up after tom is loaded - fix setting of multicast filter - enable link at device attach - exit tick handler if shutdown is in progress - add helper for logging TCB - add sysctls for dumping transmit queues
- note that TOE wxill not be MFC'd until after 7.0 has been finalized
MFC after: 3 days

Don't overload tcp_usrreqs unless the kernel doesn't provide offload support.

Make TCP offload work on HEAD (modulo negative interaction between sbcompress and t3_push_frames). - Import latest changes to cxgb_main.c and cxgb_sge.c from toestack p4 branch - make driver local copy of tcp_subr.c and tcp_usrreq.c and override tcp_usrreqs so TOE can also functions on versions with unmodified TCP
- add cxgb back to the build
