Because we already\nknow that this address will be updated in the\nhash_for_each loops, we do not need to handle it\nspecially. This removes duplicate code and simplifies\nthe i40e_vsi_add_vlan and i40e_vsi_kill_vlan functions.\nBecause we know these filters must be part of the\nMAC/VLAN hash table, this should not have any functional\nimpact on what filters are included and is merely a code\nsimplification.\n\nSigned-off-by: Jacob Keller <jacob.e.keller@intel.com>\nChange-ID: I5e648302dbdd7cc29efc6d203b7019c11f0b5705\n---\nTesting-hints:\n  Ensure that adding and removing VLANs correctly updates the filters\n  for the MAC address of the device.\n\n drivers/net/ethernet/intel/i40e/i40e_main.c | 43 +++++------------------------\n 1 file changed, 7 insertions(+), 36 deletions(-)",
