  The Rx process state is 'Waiting for packets'.
  The Tx process state is 'Idle'.
  The transmit threshold is 72.
 MII PHY found at address 1, status 0x782d.

This particular one is on a crossover @ 100 FD with a pcmcia tulip
card...which works fine.

The other machine I had reset tonight was on a crossover w/ cisco 3640
iirc.
