From 4c3f7442770b6f9b83c88f83d7d43126340ae303 Mon Sep 17 00:00:00 2001 From: Amit Cohen Date: Wed, 29 Jun 2022 12:40:06 +0300 Subject: [PATCH] mlxsw: spectrum_switchdev: Flush port from MDB entries according to FID index Currently, flushing port from all MDB entries is done when the last VLAN is removed. This behavior is inaccurate, as port can be removed while there is another port which uses the same VLAN, in such case, this is not the last port which uses this VLAN and removed, but this port is supposed to be removed from the MDB entries. Flush the port from MDB when it is removed, regardless the state of other ports. Flush only the MDB entries which are relevant for the same FID index.
