Finally got around to adding ethtool_ops to e100-3.0.x.  I found a bug
with get_eeprom() and it seems to work best if we add get_eeprom_len() to
the ops list.  Also moved check for offest + len < size into ethtool.c.

I was able to test [GS]EEPROM, PHYS_ID, GSTATS, GSTRINGS, and TEST, and
everything looks good.

Should I send same for 2.4?
