From 7b7e70f979e34ed84d725eab8ea42921ab6f42e3 Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Fri, 14 Oct 2016 05:19:20 -0400 Subject: [PATCH] qed*: Allow unicast filtering Apparently qede fails to set IFF_UNICAST_FLT, and as a result is not actually performing unicast MAC filtering. While we're at it - relax a hard-coded limitation that limits each interface into using at most 15 unicast MAC addresses before turning promiscuous. Instead utilize the HW resources to their limit.
