From 443d5a1b7d2a8727a7e7d7836a784a5decd34dc0 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 3 Dec 2016 04:35:18 +0100 Subject: [PATCH] net: dsa: mv88e6xxx: Move the tagging protocol into info Older chips support a single tagging protocol, DSA. New chips support both DSA and EDSA, an enhanced version. Having both as an option changes the register layouts. Up until now, it has been assumed that if EDSA is supported, it will be used. Hence the register layout has been determined by which protocol should be used. However, mv88e6390 has a different implementation of EDSA, which requires we need to use the DSA tagging. Hence separate the selection of the protocol from the register layout. Signed-off-by: Andrew Lunn Reviewed-by: Vivien Didelot Signed-off-by: David S.
