[PATCH] vlan: Support sending custom Ethernet CRC.

[greearb@candelatech.com]

From: Ben Greear <greearb@candelatech.com>

If the underlying device supports sending custom Ethernet CRC,
then enable that feature in the VLANs as well.

NOTE:  You will probably have to disable any
VLAN hardware assist on the underlying device to get
this to properly send packets with this feature enabled.
