From a54c4d74989b769014b359e5b66f3e571d903d25 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Mon, 25 Jul 2016 12:33:35 -0400 Subject: [PATCH 1/3] bnxt_en: Improve ntuple filters by checking destination MAC address. Include the destination MAC address in the ntuple filter structure. The current code assumes that the destination MAC address is always the MAC address of the NIC. This may not be true if there are macvlans, for example. Add destination MAC address checking and configure the filter correctly using the correct index for the destination MAC address.
