Subject: [net-next 03/14] ixgbe: remove vlan_filter_disable and enable functions

From: Jacob Keller <jacob.e.keller@...el.com>

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.
