I've attempted to backport these changes to Linux 2.6.32 as used in the
current Debian stable release. The result can be found at:
git://anonscm.debian.org/kernel/linux-2.6.git squeeze-driver-test
Please can you review the changes and test whether this works properly
(I have no hardware to test). The major difference I'm concerned about
is in VLAN handling; I'm not sure that the backported version of the
driver will configure the MAC properly for VLAN tag removal whenever it
should.

So is this fixed in the current driver version? Or are you saying that
this is a hardware bug that can't be fixed?
