Adds support to rewrite L3/L4 fields via TC-PEDIT action.
Supported fields for rewrite are:
IPv4 src/dst address, IPv6 src/dst address, TCP/UDP sport/dport.
Also, process match fields first and then process the action items.
Refactor pedit action validation to separate function to avoid
excessive code indentation.
