Based upon a report from Randy Dunlap.

The compat netdev ops assignments need to happen in
8390.c and 8390p.c, not lib8390.c, as only the type
specific code can assign the correct function pointers.

It appears that ixgbe has had a long standing bug where it was unmapping a different size than it had mapped.
