Patches are always welcome (referring to a e100 patch).

As far as the e1000 patch goes, it has a number of issues which were
found in testing.  Here are just a few problems we saw:
1. ethtool -t - crashes the system
2. ethtool eth0 - always shows link/speed as 1000/Full even when there
is no cable
3. ethtool -s eth0 autoneg on/off - system hang. Sometimes a copper
interface will show up as fiber after this.
4. ethtool -d/-S/-g etc - will corrupt the stats of the interface
while doing ifup/down

So it appears that more needs to be done to the driver to get this to
work as expected.
