This series from Matan adds ESP flow action support, the matching kernel series was already sent to rdma-next. Currently, when adding a flow steering rule, actions such as TAG or DROP could be specified in the flow action specification. However, some flow actions could be complex and needs to be shared between several flow steering rules. Therefore, we add a new flow actions mechanism. Flow actions are actions the user creates and are given as handles for the flow steering rules. We start with adding the ESP flow action, which supports both full offload and inline crypto mode. We currently only support AES_GCM crypto with bitmap replay protection. These new create, modify and destroy flow_action_esp methods are implemented using the new uverbs ioctl() infrastructure. Furthermore, the current mlx5 device works in a different way from future devices. Thus, when creating the flow action, the user has to use the mlx5dv API to specify specific driver's flags. ESP flow action is supported for both egress and ingress. Therefore, we also add a flag for egress steering in our flow steering implementation. Egress steering is currently only implemented for ESP flows. In order to carry these actions only for ESP packets, we also add an ESP match filter. Finally, we also add the required bits to support RSS for ESP flows and query the feature's support.
