Subject: [PATCH net-next 7/7] net: dsa: mv88e6xxx: use port 802.1Q mode Secure
Date: Thu, 13 Aug 2015 12:52:23 -0400 [thread overview]
Message-ID: <1439484743-5126-8-git-send-email-vivien.didelot@savoirfairelinux.com> (raw)
In-Reply-To: <1439484743-5126-1-git-send-email-vivien.didelot@savoirfairelinux.com>
This commit changes the 802.1Q mode of each port from Disabled to
Secure. This enables the VLAN support, by checking the VTU entries on
ingress.
