Re: 82576 hardware vlan tagging dysfunctional?
Brian Buhrow
since none of the other hardware assistance functions seem to work with the
82576 at this time. I believe the proble is mostly with transmition,
rather than with reception of packets.
I've been trying to figure out where in the driver these features are
tickling the chip, as opposed to notifying the upper layers of their
existence, with an eye to fixing the problem.
