From 3169241f55e194278294c7a4c43ef558c75cb0b7 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 30 Nov 2017 12:56:43 -0500 Subject: [PATCH] net: dsa: support cross-chip FDB operations When a MAC address is added to or removed from a switch port in the fabric, the target switch must program its port and adjacent switches must program their local DSA port used to reach the target switch. For this purpose, use the dsa_towards_port() helper to identify the local switch port which must be programmed. Signed-off-by: Vivien Didelot Signed-off-by: David S.
