225f5b4adc Fix t3_gate_rx_traffic and t3_open_rx_traffic. Parts of them always operated
on XGMAC0 instead of the specified XGMAC.

bd1a9fbad6 Improve cxgb(4)'s behaviour when faced with temporarily "bouncy" links:
- Run the adapter's tick at 1Hz and remove link state checks from it.
  Instead, have each port check its link state.  Delay the check so that
  it takes place slightly after the driver is notified of a change in
  link state.  This is a cheap way to debounce these notifications if
  many are received in rapid succession.  POLL_LINK_1ST_TIME flag can
  also be eliminated as a side effect of these changes.
- Do not reset the PHY when link goes down.
- Clear port's link_fault flag if the PHY indicates link is down.
- get_link_status_r should leave speed and duplex alone when link is down.

2c32b50248 Eliminate ext_intr_task. The "slow" interrupt handler is already
running on the adapter's task queue.  Just do what the task does
instead of enqueueing it.

97ae3bc359 Multiple fixes related to queue set sizing and resources:
- Only the tunnelq (TXQ_ETH) requires a buf_ring, an ifq, and the watchdog/timer
  callouts.  Do not allocate these for the other tx queues.

- Use 16k jumbo clusters only on offload capable cards by default.

- Do not allocate a full tx ring for the offload queue if the card is not
  offload capable.

- Slightly better freelist size calculation.

- Fix nmbjumbo4 typo, remove unneeded global variables.

e83ec3e5c3 There is no need to test __FreeBSD_version for features that have
been around for a long time now (7.1-ish or even earlier); assume
they are present.  These includes MSI, TSO, LRO, VLAN, INTR_FILTERS,
FIRMWARE, etc.

Also, eliminate some dead code and clean up in other places as part
of this quick once-over.

0bbdea7776 Integrate three changes from Chelsio.
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.

f2d8ff04fe Update the Chelsio driver to the latest bits from Chelsio
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)

2a1b9f07fc Several small additions to the Chelsio 10G driver.
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.
