Subject: [PATCH net-next] net: ethernet: ti: cpsw: fix the comment regarding VLAN-aware ALE

From: Alexander Sverdlin <alexander.sverdlin@...mens.com>

In all 3 cases (cpsw, cpsw-new, am65-cpsw) ALE is being configured in
VLAN-aware mode, while the comment states the opposite. Seems to be a typo
copy-pasted from one driver to another. Fix the commend which has been
puzzling some people (including me) for at least a decade.
