Some of the cbus cards are ne2000 "compatible" while others of them
are wdc "compatible".  The if_ed_cbus code to handle all of these
cases is somewhat complicated.  It would be better if that driver had
a cleaner division like netbsd's.

FreeBSD/pc98 does this a little differently.  We install i386/include
into /usr/include/i386 on pc98 machines.  pc98/machine then typically
is just #include <i386/foo.h>.  However, in the cases where there is a
difference, the file is more complicated.
