From: Maor Dickman <[email protected]>
The cited commit reserved lower tc priorities for IP ethertypes in order
to give IP traffic higher priority than other management traffic.
In case of of vlan encap traffic, IP traffic will still get lower
priority.
Fix it by also reserving low priority tc prio for vlan.
Fixes: c230c7579c14 ("netdev-offload-tc: Reserve lower tc prios for ip
ethertypes")
