- 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

Greatly simplify cxgb by removing almost all of the custom mbuf management logic
- remove mbuf iovec - useful, but adds too much complexity when isolated to the driver
- remove driver private caching - insufficient benefit over UMA to justify the added complexity and maintenance overhead
- remove separate logic for managing multiple transmit queues, with the new drbr routines the control flow can be made to much more closely resemble legacy drivers
- remove dedicated service threads, with per-cpu callouts one can get the same benefit much more simply by registering a callout 1 tick in the future if there are still buffered packets
- remove embedded mbuf usage - Jeffr's changes will (I hope) soon be integrated greatly reducing the overhead of using kernel APIs for reference counting clusters
- add hysteresis to descriptor coalescing logic
- add coalesce threshold sysctls to allow users to decide at run-time between optimizing for forwarding / UDP or optimizing for TCP
- add once per second watchdog to effectively close the very rare races occurring from coalescing
- incorporate Navdeep's changes to the initialization path required to convert port and adapter locks back to ordinary mutexes (silencing BPF LOR complaints)
- enable prefetches in get_packet and tx cleaning

- 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

Fix mbuf leak caused by freeing packet zone clusters but not their associated mbufs
- Track packet zone mbufs separately from other mbufs - free packet zone buffers via m_free rather than trying to manage the refcount as with clusters - its refcount and management seems to be "special"

- Simplify mb_free_ext_fast - increase asserts for mbuf accounting - track outstanding mbufs (maps very closely to leaked) - actually only create one thread per port if !multiq Oddly enough this fixes the use after free
- move txq_segs to stack in t3_encap - add checks that pidx doesn't move pass cidx - simplify mbuf free logic in collapse mbufs routine
