The tick routine was not being restarted in the init_locked routine
which could resulted in loss of carrier when updating the MTU.

Firmware upgraded to 7.1.0 (from 5.0.0).
T3C EEPROM and SRAM added; Code to update eeprom/sram fixed.
fl_empty and rx_fifo_ovfl counters can be observed via sysctl.
Two new cxgbtool commands to get uP logic analyzer info and uP IOQs
Synced up with Chelsio's "common code" (as of 03/03/09)

- invert sense of hw.cxgb.singleq tunable to hw.cxgb.multiq
- don't wake up transmitting thread by default
- add per tx queue ifaltq to handle ALTQ
- remove several unused functions in cxgb_multiq.c
- add several sysctls: multiq_tx_enable, coalesce_tx_enable,
and wakeup_tx_thread
- this obsoletes the hw.cxgb.snd_queue_len as ifq is replaced
by a buf_ring
1) Fix a bug in dealing with the Alerus 1006 PHY which prevented the
device from ever coming back up once it had been set to down.
2) Add a kernel tunable (hw.cxgb.snd_queue_len) which makes it possible
to give the device more than IFQ_MAXLEN entries in its send queue. The
default remains 50.
3) Add code to place the card'd identification and serial number into
its description (%desc) so that users can tell which card they have
installed.
- add / remove clients from cxgb_main.c now
- change ifdef TOE_ENABLED to TCP_OFFLOAD_DISABLE
- update copyrights
- fix transmit data mismatch bug caused by not setting SB_NOCOALESCE
on tx sockbuf on passive connections
- fix receive sequence mismatch bug caused by not setting SB_NOCOALESCE
on rx sockbuf on passive connections
- don't sleep without checking SBS_CANTRCVMORE first
- various ddp ordering fixes
Supported by: Chelsio Inc.
move most offload functionality from NIC to TOE
factor out all socket and inpcb direct access
factor out access to locking in incpb, pcbinfo, and sockbuf
- 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

- move cxgb_tx_common in to cxgb_multiq.c and rename to cxgb_tx
- move cxgb_tx_common dependencies
- further simplify cxgb_dequeue_packet for the non-multiqueue case
- only launch one service thread per port in the non-multiq case
- remove dead cleaning code from cxgb_sge.c
- simplify PIO case substantially in by returning directly from mbuf collapse
and just using m_copydata
- remove gratuitous m_gethdr in the rx path
- clarify freeing of mbufs in collapse
- 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
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
- 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

- 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
