- 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

MFtbemd:
Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the source code location of the machine, the latter the binary output. In general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless we're tesitng for a specific target. The isn't even moot for i386/amd64 where there's momemntum towards a MACHINE_CPUARCH == x86, although a specific cleanup for that likely would be needed...

This main goals of this project are: 1. separating L2 tables (ARP, NDP) from the L3 routing tables 2. removing as much locking dependencies among these layers as possible to allow for some parallelism in the search operations 3. simplify the logic in the routing code,
The most notable end result is the obsolescent of the route cloning (RTF_CLONING) concept, which translated into code reduction in both IPv4 ARP and IPv6 NDP related modules, and size reduction in struct rtentry{}. The change in design obsoletes the semantics of RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland applications such as "arp" and "ndp" have been modified to reflect those changes. The output from "netstat -r" shows only the routing entries.
Quite a few developers have contributed to this project in the past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and Andre Oppermann. And most recently:
- Kip Macy revised the locking code completely, thus completing the last piece of the puzzle, Kip has also been conducting active functional testing - Sam Leffler has helped me improving/refactoring the code, and provided valuable reviews - Julian Elischer setup the perforce tree for me and has helped me maintaining that branch before the svn conversion

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

- switch over to standard method for initializing cdevs (contributed by scottl@) - break out timer_reclaim_task to be per-port - move msix teardown into separate function - fix bus_setup_intr for msi-x for the multi-port case so that msi-x resources are not corrupted on unload - handle 10/100/1000 base-T media and auto negotiation - bind qset to cpu even for singleq case - white space cleanups - remove recursive PORT_LOCK - move mtu setting to separate function - stop and re-init port when changing mtu - replace all direct references to m_data with calls to mtod - handle attach failure better by not trying to de-initialize taskqueues when they have not been allocated - no longer default to jumbo frames
