Subject: [PATCH net-next 0/8] cxgb4: enable more tc flower offload matches and actions

This patch series enable more matches and actions for TC Flower
Offload support on Chelsio adapters.

Patch 1 enables matching on IP TOS.

Patch 2 enables matching on VLAN TCI.

Patch 3 adds support for action PASS.

Patch 4 adds support for ETH-DMAC rewrite via TC-PEDIT action. Also,
adds a check to assert that vlan/eth-dmac rewrite actions are valid
only in combination with action egress redirect.

Patch 5 introduces SMT ops for adding/removing entries from SMAC Table
in HW in preparation for patch 6.

Patch 6 adds support for ETH-SMAC rewrite via TC-PEDIT action.

Patch 7 introduces fw_filter2_wr to support L3/L4 header rewrites
in preparation for patch 8.

Patch 8 adds support for rewrite on L3/L4 header fields via TC-PEDIT
action. Supported fields for rewrite are:
IPv4 src/dst address, IPv6 src/dst address, TCP/UDP sport/dport.

Thanks,
Rahul
