Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle. Prune svn:mergeinfo from the new branch, as nothing has been merged here.
Additional commits post-branch will follow.

- 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

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
