[dpdk-dev] [PATCH v2 06/14] net/ice/base: change protocol ID for VLAN in case of DVM

[Qi Zhang]

Protocol id for first vlan in Double VLAN Mode (DVM) should be
ICE_VLAN_OF_HW = 16, but for Single VLAN Mode (SVM) this should be
ICE_VLAN_OL_HW = 17.

Change protocol id in type to id translation array for outer vlan
to 17 when DVM is enabled, which means the driver, package,
and firmware support DVM.
