Hi,
this morning, I tried upgrading a firewall from Debian woody to Debian
sarge, and in the course upgrading from a locally compiled vanilla 2.4.30
to a locally compiled vanilla 2.6.12.2. The box is a hp DL 140 which has
two tg3-based Interfaces on board, and a dual-Interface E1000 PCI card in
its PCI slot:

The box uses dot1q VLANs on all interfaces.
After rebooting, the VLANs on the Intel-based interfaces worked fine, while
the tg3-based interfaces didn't answer to tagged ARP requests. The untagged
VLAN on the tg3-based interfaces was fine as well. When tcpdumping the
subinterfaces, I saw all traffic on the network, and especially the
incoming ARP requests, but no ARP replies went out.
Rebooting back to 2.4 solved the issue immediately, all VLANs were OK as
well.
Conclusion: Since the e1000-based VLANs work fine even with 2.6, the dot1q
code seems to be ok. So, the issue most probably lies with the tg3 driver.
I am pretty well aware that there are issues with tg3 on _Debian_ kernels,
which is one of the reasons why I use locally compiled kernels built from
vanilla kernel.org sources.
Any hints?
Greetings
Marc
