SVN rev 207720 on 2010-05-06 18:44:49Z by yongari
MFC r207409,207442:
r207409:
Both RX_GMF_LP_THR and RX_GMF_UP_THR must be 16 bits register. If
it is 8bits register then RX FIFO size can't exceed 2KB which is
not true for almost all Yukon II controller.
r207442:
Disable non-ASF packet flushing on Yukon Extreme as vendor's driver
does. Without this change, Yukon Extreme seems to generate lots of
RX FIFO overruns even though controller has available RX buffers.
These excessive RX FIFO overruns generated lots of pause frames
which in turn killed devices plugged into switch. It seems there is
still occasional RX frame corruption on Yukon Extreme but this
change seems to fix the pause frame storm.
