[dpdk-dev] [PATCH v3 14/14] net/ice/base: allow support for GTP-U filter using only inner protocols

[Qi Zhang]

Adds a support for switch filter: GTP-U using just inner fields.
If user doesn't specify outer protocol and its fields but wants to
add switch filter for GTP-U using inner protocols and related fields
such as inner L3 and/or inner L4, this patch enables such filtering.
