Add some padding to struct ifmibdata and move the `struct ifdata' to

the end of that sstructure to make evolution easier.

Add definitions for the 802.3/Ethernet MIB.  To implement this, simply
add a `struct ifmib_iso_8802_3' somewhere in your interface's softc,
point if_linkmib to it, set if_linkmiblen, and fill in the statistics
with appropriate values.  (I didn't want to create Yet Another Ethernet-
related header file, otherwise this would have been separated out.)
