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.
