From 6a7e69936992104e7abbf12c7f619a39bf139a48 Mon Sep 17 00:00:00 2001 From: Yashaswini Raghuram Prathivadi Bhayankaram Date: Fri, 26 Oct 2018 11:44:41 -0700 Subject: [PATCH] ice: Do not set LAN_EN for MAC-VLAN filters In the action fields for a MAC-VLAN filter, do not set the LAN_EN flag if the MAC in the MAC-VLAN is unicast MAC. The unicast packets that match should not be forwarded to the wire.
