[PATCH net-next 3/8] net: hns3: set default mac vlan mask

[Lipeng]

Add the mask configuration of the MAC_VLAN table. Command
HCLGE_OPC_MAC_VLAN_MASK_SET is used to add/read the mask
configuration of the MAC_VLAN (u/m vlan) table. Set default mask
as {0x00, 0x00, 0x00, 0x00, 0x00, 0x00} means that all bits of
mac_vlan are not masked.
