This patch series adds support for tc hardware offloads. Patch #1 adds support for offloading flows that matches IP tos and IP protocol which will be used by tc hw offload support. Also added ethtool n-tuple filter to code to offload the flows matching the above fields. Patch #2 adds tc flower hardware offload support on ingress traffic. Patch #3 adds TC flower offload stats. Patch #4 adds tc TC_MATCHALL egress ratelimiting offload. * tc flower hardware offload in PF driver The driver parses the flow match fields and actions received from the tc subsystem and adds/delete MCAM rules for the same. Each flow contains set of match and action fields. If the action or fields are not supported, the rule cannot be offloaded to hardware. The tc uses same set of MCAM rules allocated for ethtool n-tuple filters. So, at a time only one entity can offload the flows to hardware, they're made mutually exclusive in the driver. Following match and actions are supported. Match: Eth dst_mac, EtherType, 802.1Q {vlan_id,vlan_prio}, vlan EtherType, IP proto {tcp,udp,sctp,icmp,icmp6}, IPv4 tos, IPv4{dst_ip,src_ip}, L4 proto {dst_port|src_port number}. Actions: drop, accept, vlan pop, redirect to another port on the device. The Hardware stats are also supported. Currently only packet counter stats are updated. * tc egress rate limiting support Added TC-MATCHALL classifier offload with police action applied for all egress traffic on the specified interface.
