[dpdk-dev] [PATCH v3 08/10] net/mlx5: update translate function for mirror

Jiawei Wang jiaweiw at nvidia.com
Tue Oct 13 16:11:50 CEST 2020


Translate the attribute of sample action that include sample ratio
and sub actions list.
PMD will check the destination action number in current flow,
if found multiple destination actions, then create the new destination
array rdma action that group actions for each destination.
Currently only support port or queue for destination action, and only
encap action can be attached into one port destination.
