CVS commit: src/sys/dev/pci

[Jason R Thorpe <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej

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

Log Message:
- Dump the mbuf chain if we encounter a "too many DMA segments" error
  on transmit.
- On 82544 and up, allocate 4096 Tx descriptors rather than just 256.
  82543 and down must still use 256, due to errata.
- Allow up to 256 DMA segments per packet.  I have observed some truly
  pathological mbuf chains under certain (admittedly uncommon) workloads
  when jumbo frames are in use.
