From 58184b8ff0786b219772016a50ce07c6b3020846 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Wed, 18 Mar 2020 16:00:53 -0700 Subject: [PATCH] igc: Change igc_add_mac_filter() returning value In case of success, igc_add_mac_filter() returns the index in adapter->mac_table where the requested filter was added. This information, however, is not used by any caller of that function. In fact, callers have extra code just to handle this returning index as 0 (success). So this patch changes the function to return 0 on success instead, and cleans up the extra code.
