Chris, I took a look at this with Carolyn and I believe what you're seeing is the expected behavior. In these older kernels, there was no ethtool option to turn on and off VLAN stripping on the fly. If you look, the get_flags operation just calls ethtool_op_get_flags, which doesn't recognize ETH_FLAG_RXVLAN. If you're seeing issues with the functionality of VLANs with igb alone, let us know and we'll take a look at it.
