[dpdk-dev] [PATCH v3 21/53] net/ice/base: allow GENEVE and VXLAN rules with VLAN

[Qi Zhang <qi.z.zhang@intel.com>]

When programming GENEVE and VXLAN switch rules, there are some instances
where both VLAN tagged packets plus non-VLAN tagged packets are needed
to match the rule.

In order to perform this action in one rule, the switch code needs
to setup the packet flag mask to ignore the VLAN packet flag. This
will allow the rule to match both VLAN and non-VLAN packets.
