[dpdk-dev] [PATCH v3] net/mlx5: rewrite IP address UDP/TCP port by E-Switch

Jack Min jackmin at mellanox.com
Thu Oct 11 11:26:42 CEST 2018


Offload the following rte_flow actions by inserting accordingly
E-Switch rules via TC Flower driver

 - RTE_FLOW_ACTION_TYPE_SET_IPV4_SRC
 - RTE_FLOW_ACTION_TYPE_SET_IPV4_DST
 - RTE_FLOW_ACTION_TYPE_SET_IPV6_SRC
 - RTE_FLOW_ACTION_TYPE_SET_IPV6_DST
 - RTE_FLOW_ACTION_TYPE_SET_TP_SRC
 - RTE_FLOW_ACTION_TYPE_SET_TP_DST

The example testpmd command is:

    flow create 0 transfer ingress
         pattern eth / ipv4 / udp dst is 7000 / end
	 actions set_ipv4_src ipv4_addr 172.168.0.1 /
	 set_ipv4_dst ipv4_addr 172.168.10.1 /
	 set_tp_dst port 9000 /
	 set_tp_src port 700 /
	 port_id id 1 / end

v2:
 * rebased
 * validate pedit actions with drop action
 * validate successive pedit actions
 * a more generic way of validation
 * added testpmd commands in commit log
 * added comments of new added functions
 * fix some coding style issue
v3:
 * fix some coding style issue
 * calc pedit keys become macro
