Dear linux-net, I'm running the stock kernel of Ubuntu Hardy: 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:06 UTC 2008 x86_64 GNU/Linux My eth0 is: driver: e1000e version: 0.3.3.3-k6 firmware-version: 2.1-12 bus-info: 0000:04:00.0 If have several VLANs configured on eth0, such as: eth0.105 eth0.106 eth0.107 When I run tcpdump on each, I can see the traffic for the respective VLAN. When I tcpdump eth0, I can see the traffic for *all* the VLANs. So far so good. Except, when I look at the traffic for all the VLANs, the VLAN ID is not present. Many hours of googling, looking at the e1000e driver code and VLAN code, and picking other ppl's brains, has led me to believe that VLAN hardware acceleration is stripping the tag from the frame, so I can't actually see the VLAN ID. So my question is, is it possible to turn hwaccel off for this card without hacking and recompiling the driver? Or can I get the VLAN ID using some other method that I don't know about? Also, some of code and commit messages I've read seem to indicate even if tcpdump could show me the VLAN ID, I wouldn't necessarily get any of this traffic unless eth0 is in promisc mode. My main goal here is to be able to bridge eth0 to another device and ensure that that device can see all the tagged traffic that comes in eth0. eth0 is plugged into a Cisco switch and is a trunk port.
