ixl(4) supports ETHERCAP_VLAN_HWTAGGING
It is enabled by defualt
The features is realized by the following operations:
- internal switch

- TX
- set VLAN tag and IL2TAG1 flag to each descriptor
- RX
- use 32byte descriptor to use SHOWIV and L2SEL flag
included in RX queue configuration
- VLAN tags are not stored in descriptor without these config.
- get VLAN tags from L2TAG1 field included in RX descriptor
and set them to mbuf
