- 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

1) Add a sysctl that will say what type of PHYs exist on the card.
2) Fix a bug that occurs when an AEL 2005 PHY resets without a transciever
in the card.
3) Unify the PHY link detection code.

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

recieves data it mistakenly thinks that its transmitting side is broken
and resets the device.

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.

spin forever in the taskq thread
- remove unused rxsd_ref
- simplify header_offset calculation for embedded mbuf headers

- 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
