From 22025588e48394ccf557bd3cd1645a95a15a155d Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Wed, 8 Mar 2017 01:18:50 -0500 Subject: [PATCH] net/fm10k/base: reset multicast mode when deleting lport Deleting lport when multicast mod is configured to FM10K_XCAST_MODE_ALLMULTI or FM10K_XCAST_MODE_PROMISC will result in generating orphaned multicast-group entries in the switch manager. Before deleting the lport, reset multicast mode to FM10K_XCAST_MODE_NONE to flush out these multicast-group entries.
