Log Message:
Don't attempt to do transmit threshold tuning on the Lite-On PNCI; just
put it in Store-and-Forward mode right from the get-go.  This eliminates
the DMA underrun errors that prevented the receive filter setup from working
and caused smashed packets to go out onto the wire.

My NetGear FA310-TX board now works.

There are still "filter setup failed to complete" messages, however they
don't appear to indicate that the filter setup actually failed, since
unicast and multicast packet reception work fine.  I will address this
problem shortly.

Reading the log for the FreeBSD `pn' driver suggests that these chips are,
in fact, pretty crappy, riddled with hardware bugs (for which more workarounds
are coming).
