    sys/pci              if_dc.c if_dcreg.h 
    sys/dev/mii          dcphy.c 
  Log:
  Fix some problems reported by Mike Pritchard:
  
  - Add a flag DC_TX_INTR_ALWAYS which causes the transmit code to
    request a TX done interrupt for every packet. The PNIC seems to need
    this to insure that the sent TX buffers get reaped in a timely fashion.
  
  - Try to unreset the SIA as soon as possible after resetting the whole
    chip.
  
  - Change dcphy to support either 10/100 or 10Mbps only NICs. The
    built-in 21143 ethernet in Compaq Presario machines is 10Mbps only
    and it doesn't work right if we try to advertise 100Mbps modes during
    autoneg. When restricted to only 10mbps modes, it works fine.
  
    Note that for now, I detect this condition by checking the PCI
    subsystem ID on this NIC (which has a Compaq vendor/device ID).
    Yes, I know that's what the SROM is supposed to be for. I'm deliberately
    ignoring the SROM wherever possible. Sue me.
  
  The latter two fixes allow if_dc to work correctly with the built-in
  ethernet on certain Compaq Presario boxes. There are liable to be quite
  a few people using these as their home systems who might want to try
  FreeBSD; may as well be nice to them.
  
  Now if anybody out there has an Alpha miata with 10Mbps ethernet and
  can show me the output from pciconf -l on their system, I'd be grateful.
