[dpdk-stable] [PATCH 20.11 v2 13/18] net/ice/base: add inner VLAN protocol type for QinQ filter

[Haiyue Wang <haiyue.wang@intel.com>]

From: Qi Zhang <qi.z.zhang@intel.com>

[ upstream commit 0475c7770502cb4166b2577df3ff446af9d85515 ]

Since VLAN protocol type 'ICE_VLAN_OFOS' has been changed to map
the hardware VLAN protocol ID to 'ICE_VLAN_OF_HW (16)' when in Double
VLAN mode, and to 'ICE_VLAN_OL_HW (17)' when in Single VLAN mode.

So 'ICE_VLAN_OFOS' can't be used with 'ICE_VLAN_EX' which is outer VLAN
hardware protocol ID 'ICE_VLAN_OF_HW (16)' to do the QinQ VLAN pattern.

Introduce the new inner VLAN protocol type 'ICE_VLAN_IN', which is inner
VLAN hardware protocol ID 'ICE_VLAN_OL_HW (17)'.

Now for QinQ VLAN pattern, the protocol 'ICE_VLAN_EX' and 'ICE_VLAN_IN'
should be used to set the related protocol header fields like VLAN ID.
