vlan: restore ethtool ABI to control VLAN hardware acceleration
As part of the push to add 802.1ad server provider tagging support to the kernel the VLAN features flags were renamed. Unfortunately the kernel name for the VLAN hardware acceleration features that the kernel shows user space was included in the rename, which broke ethtool (txvlan and rxvlan options do not work). This patch restores the original names, i.e. the original ABI. If we wanted to make clear to users that we are refering to CTAGs we can always change ethtool's short_name and long_name for these features (for example something along the lines of txvlan -> txvlan-ctag, tx-vlan-offload -> tx-vlan-ctag-offload).
