From a9b8943ee129e11045862d6d6e25c5b63c95403c Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Tue, 25 Mar 2014 07:45:26 +0000 Subject: [PATCH] ixgbe: remove vlan_filter_disable and enable functions Previously these functions handled stripping setup as well, but this has already been removed from these functions. Rather than encapsulating this into a function, we can just do the work directly in set_rx_mode.
