f001b63dcb - make 9k clusters the default unless a tunable is set
- return the error from cxgb_tx_common so that when an error is hit we dont
  spin forever in the taskq thread
- remove unused rxsd_ref
- simplify header_offset calculation for embedded mbuf headers
- fix memory leak by making sure that mbuf header initialization took place
- disable printf's for stalled queue, don't do offload/ctrl queue restart
  when tunnel queue is restarted
- add more diagnostic information about the txq state
- add facility to dump the actual contents of the hardware queue using sysctl

b6ae6984e8 Don't duplicate the whole of arpresolve to arpresolve 2 for the sake
of two compares against 0. The negative effect of cache flushing
is probably more than the gain by not doing the two compares (the
value is almost certainly in register or at worst, cache).
Note that the uses of m_freem() are in error cases and m_freem()
handles NULL anyhow. So fast-path really isn't changed much at all.

8090c9f504 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

45c5d90b65 Evidently setup_rss needs to happen whenever bind_qsets is done. This fixes
a problem with jumbo frames when not using msi-x interrupts.

5c5df3da16 - fix qset to port binding as a proper fix for the problems encountered on the 4-port
- fix the use after free seen when sending packets small enough to fit as an immediate
   and bpf peers are present
 - update to firmware rev 4.7 along with various small vendor fixes

7ac2e6c362 Fixes for 4 port and small packet optimization
- remove cpl->iff panic - we can't know the port number from the rspq on the 4-port
- pick the ifnet based on the interface in the CPL header
- switch to using qset 0 for egress on the 4-port for now - may change
  when we start using RSS
- move ether_ifdetach to before the port lock gets deinitialized to avoid
  hang in the case where there are BPF peers (cxgb_ioctl is called indirectly
  when BPF peers are present)
- don't call t3_mac_reset if multiport is set, this was causing tx errors
  by misconfiguring the MAC on the 4-port
- change V_TXPKT_INTF to use txpkt_intf as the interfaces are not contiguous
- free the mbuf immediately in the case where the payload is small enough to be copied
  into the rspq
- only update the coalesce timer if for a queue if packets were taken off of it
- add in missed 20ms DELAY in initializaton vsc8211

- prompt MFC as this only applies to the 4-port which is currently completely
  broken - OK'd by kensmith

- reduce cpu usage by as much as 25% (40% -> 30) by doing txq reclaim more efficiently
   - use mtx_trylock when trying to grab the lock to avoid spinning during long encap loop
   - add per-txq reclaim task
   - if mbufs were successfully re-claimed try another pass
- track txq overruns with sysctl

bb38cd2fbc - switch adapter and port lock over to using sx so that resources
can be allocated atomically
- add debug macros for printing lock initialization / teardown
- add buffers to port_info and adapter to allow each lock to have a
  unique name
- destroy mutexes initialized by cxgb_offload_init
- remove recursive calls to ADAPTER_LOCK
- move callout_drain calls so that they don't occur with the lock held
- ensure that only as many qsets as are needed are initialized and
  destroyed
