2017-11-01cxgb4: convert flower table to use rhashtableKumar Sanghvi1-2/+2
T6 supports ~500K hash filters and can theoretically climb up to ~1 million hash filters. Preallocated hash table is not efficient in terms of memory usage. So, use rhashtable instead which gives the flexibility to grow based on usage.

2017-10-20cxgb4: add tc flower support for L3/L4 rewriteKumar Sanghvi1-0/+32
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.
