VLAN filtering was always performed, even if hw_vlan_filter was
disabled. During device initialization, default filter
RTE_MACVLAN_PERFECT_MATCH was applied. In this situation, all incoming
VLAN frames were dropped by the card (increase of the register RUPP - Rx
Unsupported Protocol).
In order to restore default behavior, if HW VLAN filtering is activated,
set a filter to match MAC and VLAN. If not, set a filter to only match
MAC.

Changes since v2:
- switch log level from INFO to ERR in case of failure
Changes since v1:
- use ether_addr_copy() for mac copy
- add more debug messages in case of failure
- update all existing filters when multiple mac addresses have been configured
- when adding new mac address, use correct filter
TODO:
- i40e_update_default_filter_setting always forces to
RTE_MACVLAN_PERFECT_MATCH.
=> The type of filter should be changed according to vlan filter setting.
- What happens if vlan filter setting changes when various filters are already
set like RTE_MACVLAN_PERFECT_MATCH, RTE_MACVLAN_PERFECT_MATCH,
RTE_MAC_HASH_MATCH, RTE_MACVLAN_HASH_MATCH ?
=> With testpmd, it is possible to add manually these filters. But when
changing vlan filter setting, all previous filter set manually are overriden.
