Rework interrupt bringup and teardown.

Calculate the exact number of vectors we'll use before calling
pci_alloc_msix. Don't grab nine all the time.

Call cxgb_setup_interrupts once per T3, not once per port. Ditto
for cxgb_teardown_interrupts.

Don't leak resources when interrupt setup fails in the middle.

and down more cleanly. This addresses a problem where if we have the
link flap during boot the driver would lock up the system.

Fix a bug in the recent update to the Chelsio driver.
The tick routine was not being restarted in the init_locked routine
which could resulted in loss of carrier when updating the MTU.

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
