On Fedora 3.3 kernel I see the same problem. tcpdumping the physical
network interface eth0, I can see the DHCP replies coming through
clearly, on VLAN 103, but tcpdumping eth0.103 (the trunked VLAN
interface #103 associated to eth0), the DHCP replies simply do not
appear. In both tcpdumps, the D

magellan, thank you for reporting this and helping make Ubuntu better. Maverick
reached EOL on April 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
We were wondering if this is still an issue on a supported release? If
so, can you try with
A bit more testing.
The vlan-offload support does not make any difference (tested on old
hardware)
Installing kernel 2.6.38-10 (from lucid-updates) on a running lucid
(10.04) system did break the vlan interface and a network bridge running
on a vlan interface.
vlan support is now working on my o
vlan support is still broken in the oneiric beta.
But ethtool does give a clue:
ethtool -k eth0
rx-vlan-offload: on
tx-vlan-offload: on
Older kernels (2.6.32-33) do not have vlan-offload support. The vlan
support in Ubuntu fails once you use a kernel which does have vlan
offloading. Ethtool fail
This is still un-assigned and doesn't appear to have been worked on. I
rely heavily on vlan support. Has there been any movement on this, or
is there at least a work-around in the works?

VLAN interfaces (e.g., eth0.2) work for me in 2.6.35-28-generic, but are
broken past that. 2.6.37-* is broken as well as 2.6.38-* in (soon to be
released) natty. Sporadic packet loss in reception of packets. Seems
they get lost in the stack somewhere. Turning off generic-segmentation-

It seems that nobody cares...
For those who also have this issue, falling back to the 10.04 kernel
seems to be a valid workaround.

Title:
VLAN s
I performed a fresh install of Ubuntu 10.10 Desktop on the laptop and
the problem remains exactly the same.
Tagged outgoing traffic is working fine. Incoming tagged traffic showing
up on the physical interface (eth0) but not on the VLAN interface
(eth0.x).
Untagged traffic is working fine.

These symptoms seems similar to mine with a little extra twist.
When adding a vlan to a bonding interface, all vlan tagged broadcasts
seems to arrive twice on the bonding interface according to tcpdump.
Remove the vlan and the double packets stop.
Ie.
modprobe bonding mode=1 miimon=100
ip link s
I can confirm precisely these symptoms with 2.6.35-22. I can see the
VLAN packets going out, and I can see the responses leaving a remote
system (ARP in this case), but they (responses) do not appear on the
Maverick box interface according to tcpdump.
Reverting to 2.6.32 (Lucid) solves problem.
