Subject: [dpdk-dev] [PATCH v2 2/7] net/mlx5: e-switch VXLAN flow validation routine
Date: Mon, 15 Oct 2018 14:13:30 +0000
Message-ID: <1539612815-47199-3-git-send-email-viacheslavo@mellanox.com> (raw)
In-Reply-To: <1539612815-47199-1-git-send-email-viacheslavo@mellanox.com>

This part of patchset adds support for flow item/action lists
validation. The following entities are now supported:

- RTE_FLOW_ITEM_TYPE_VXLAN, contains the tunnel VNI

- RTE_FLOW_ACTION_TYPE_VXLAN_DECAP, if this action is specified
  the items in the flow items list treated as outer network
  parameters for tunnel outer header match. The ethernet layer
  addresses always are treated as inner ones.

- RTE_FLOW_ACTION_TYPE_VXLAN_ENCAP, contains the item list to
  build the encapsulation header. In current implementation the
  values is the subject for some constraints:
    - outer source MAC address will be always unconditionally
      set to the one of MAC addresses of outer egress interface
    - no way to specify source UDP port
    - all abovementioned parameters are ignored if specified
      in the rule, warning messages are sent to the log
