[dpdk-dev] [PATCH v2 07/15] net/mlx5: support tunnel RSS level
Xueming Li
xuemingl at mellanox.com
Tue Apr 10 15:34:07 CEST 2018
Tunnel RSS level of flow RSS action offers user a choice to do RSS hash
calculation on inner or outer RSS fields. Testpmd flow command examples:
GRE flow inner RSS:
flow create 0 ingress pattern eth / ipv4 proto is 47 / gre / end
actions rss queues 1 2 end level 1 / end
GRE tunnel flow outer RSS:
flow create 0 ingress pattern eth / ipv4 proto is 47 / gre / end
actions rss queues 1 2 end level 0 / end
