Subject: [net-next v2 06/14] i40e: when adding or removing MAC filters, correctly handle VLANs

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

Instead of using i40e_add_filter or i40e_del_filter directly, when
adding a MAC address, we should normally be using i40e_add_mac_filter or
i40e_del_mac_filter. These functions correctly handle the various cases
of VLAN mode or PVID settings. This ensures consistency and avoids the
issues that can occur with the recent addition of a WARN_ON() in
i40e_sync_vsi_filters.
