From ea70ba980666cffacb57d90d867b2c7952d90700 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 22 Oct 2015 09:34:38 -0400 Subject: [PATCH] net: dsa: add port_fdb_dump function Not all switch chips support a Get Next operation to iterate on its FDB. So add a more simple port_fdb_dump function for them. Signed-off-by: Vivien Didelot Signed-off-by: David S.
