Subject: [PATCH net] net: dsa: point out the tail taggers

>From a  recent commit with the same summary:

"The Marvell 88E6060 uses tag_trailer.c and the KSZ8795, KSZ9477 and
KSZ9893 switches also use tail tags."

Set "tail_tag" to true for KSZ8795 and KSZ9477 which were missing in the
original commit.

Fixes: 7a6ffe764be3 [net] ("net: dsa: point out the tail taggers")
