Modified Files:
        syssrc/sys/dev/pci: if_wm.c

Log Message:
* Deal with errata on the i82542 and i82543 chips: The size of the
  transmit and receive descriptor rings is limited to 256 descriptors.
  So, set the if_snd queue length to 256 to let the upper layers queue
  lots of packets, and let the driver handle up to 32 of them at a time.
  (We should probably make this change to most Ethernet drivers, since
  it actually saves some resources.)
* Increase the number of Tx DMA segments from 8 to 16.
* Clean up the way we count "how many times did I get a packet with N
  DMA segments".
* Add a missing htole32() in wm_tx_cksum().
* Don't set both RS and RPS in the last Tx descriptor of a packet; just
  use RS.
* Add some more information to the watchdog message.
