tg3: Do not include vlan acceleration features in vlan_features
[ Upstream commit 51dfe7b944998eaeb2b34d314f3a6b16a5fd621b ]
Including hardware acceleration features in vlan_features breaks
stacked vlans (Q-in-Q) by marking the bottom vlan interface as
capable of acceleration. This causes one of the tags to be lost
and the packets are sent with a sing vlan header.
