e100: make sure vlan support isn't advertised on old adapters

e100: make sure vlan support isn't advertised on old adapters

e100 parts don't support vlan offload but they generally do
allow use of vlans in higher software layers via the 8021q module.
That said, there are a couple of really old revisions of e100
hardware that don't even allow the longer frame sizes
required for vlan use with standard MTU.

Use the VLAN_CHALLENGED flag to prevent vlan binding to these
devices.
