[vortex] RX overrun with 3COM 3c982

[Donald Becker]

OK, I have a new test version 3c59x.c (and an updated vortex-diag.c)
that should handle this overload dynamically.

I'll announce them on both driver-announce and vortex-announce in a few
minutes.

Please try the new driver:

...
Dynamically increase the RxPriorityThresh on every a Rx FIFO overrun.
  The default value is 4*32 bytes
  We increase it by 32 bytes up to 31*32 bytes.
  If Rx FIFO overruns continue we want on each corrupted packet!
