#10429 fixed e1000 VLAN encapsulation not working fused
Description

Probably because vlan tagging code is in the driver, but hardware (virtualbox) doesn't support it.

2.6.18-308.1.4.el5.fusedxen #1 SMP x86_64
#
modinfo e1000 |grep versio
version:        7.3.21-k4-3-NAPI
srcversion:     F036629BEA728AD54A09602

How to reproduce:

  1. Create/attach vlan with vconfig add eth0 1234
  2. ip ad add 192.168.0.1/24 dev vlan1234
  3. tcpdump -n -e -i eth0 &
  4. ping 192.168.0.123
  5. fg ; # no 802.1q encapsulation seen in capture

Workaround:

  • select a different, older/dumber network card in VM prefs
