NetBSD/sys/dev/pci/if_fxpvar.h
thorpej f2317e1c5b Changes to support NetBSD, written by me, tested by Matthias Drochner:
- Add NetBSD autoconfiguration support.
- Rearrange code slightly to minimize the number of #ifdefs.
- Don't use a structure to access CSRs.  Use macros that DTRT for
  the NetBSD and FreeBSD cases.
- Deal with alignment contraint on Alpha - add 2-byte padding at the
  beginning of the RFA, so that the data will be 4-byte aligned, after
  the 14-byte Ethernet header.
Thanks to Matthias Drochner for the testing, and David Greenman for
the feedback on the changes.
