From 38fbe91f2287c696f290d9115901aa435f7166a8 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Mon, 24 May 2021 16:14:20 +0300 Subject: [PATCH] net: dsa: sja1105: configure the multicast policers, if present The SJA1110 policer array is similar in layout with SJA1105, except it contains one multicast policer per port at the end. Detect the presence of multicast policers based on the maximum number of supported L2 Policing Table entries, and make those policers have a shared index equal to the port's default policer. Letting the user configure these policers is not supported at the moment. Signed-off-by: Vladimir Oltean Signed-off-by: David S.
