Commit Message

Zhang, Qi Z April 13, 2021, 2:30 p.m. UTC
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.
