Subject: [PATCH net-next v2 13/18] net: dsa: mv88e6xxx: add VTU GetNext operation
Date: Mon, 1 May 2017 14:05:22 -0400 [thread overview]
Message-ID: <20170501180527.11756-14-vivien.didelot@savoirfairelinux.com> (raw)
In-Reply-To: <20170501180527.11756-1-vivien.didelot@savoirfairelinux.com>
Add a new vtu_getnext operation to the chip info structure to differ the
various implementations of the VTU accesses.
