Subject: [PATCH net 2/6] net: dsa: ksz: move tag/untag action
Date: Wed, 13 Jan 2021 13:45:18 +0100	[thread overview]
Message-ID: <8e1cd9b167bd39c0f82ca8970a355cdfbc0fe885.1610540603.git.gilles.doffe@savoirfairelinux.com> (raw)
In-Reply-To: <cover.1610540603.git.gilles.doffe@savoirfairelinux.com>

Move tag/untag action at the end of the function to avoid
tagging or untagging traffic if only vlan 0 is handled.
