/* lasi_82596.c -- driver for the intel 82596 ethernet controller, as
munged into HPPA boxen .
This driver is based upon 82596.c, original credits are below...
but there were too many hoops which HP wants jumped through to
keep this code in there in a sane manner.
3 primary sources of the mess --
1) hppa needs *lots* of cacheline flushing to keep this kind of
MMIO running.
2) The 82596 needs to see all of its pointers as their physical
address. Thus virt_to_bus/bus_to_virt are *everywhere*.
3) The implementation HP is using seems to be significantly pickier
about when and how the command and RX units are started. some
command ordering was changed.
Examination of the mach driver leads one to believe that there
might be a saner way to pull this off... anyone who feels like a
full rewrite can be my guest.
