Poll for link state when the link is down, even for interrupt capable
PHYs.
Allow PHYs to report a dubious "partial" link. If this state is seen 3
consecutive times (each check is ~1s apart) then reset the PHY. This is
a workaround for a situation where repeatedly toggling the link from the
peer gets the AEL2005 PHY into a state where it never establishes a PCS
block lock even when everything is in order.

- 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.

- 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.

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.

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
Synced up with Chelsio's "common code" (as of 03/03/09)

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.
