Tunnel offload implementation introduced 64 bit-field flow_grp_info

type by value in function calls.
The patch changes that structure passing method to reference.

* Split action list having QUEUE/RSS for metadata register copy.
|
|
*
|
|
* Once Q/RSS action is detected in user's action list, the flow action
|
|
* should be split in order to copy metadata registers, which will happen in
|
|
* RX_CP_TBL like,
|
|
* - CQE->flow_tag := reg_c[1] (MARK)
|
|
* - CQE->flow_table_metadata (reg_b) := reg_c[0] (META)
|
|
* The Q/RSS action will be performed on RX_ACT_TBL after passing by RX_CP_TBL.
|
|
* This is because the last action of each flow must be a terminal action
|
|
* (QUEUE, RSS or DROP).
|
|
*
|
|
* Flow ID must be allocated to identify actions in the RX_ACT_TBL and it is
|
|
* stored and kept in the mlx5_flow structure per each sub_flow.
|
|
*
|
|
* The Q/RSS action is replaced with,
|
|
* - SET_TAG, setting the allocated flow ID to reg_c[2].
|
|
* And the following JUMP action is added at the end,
|
|
* - JUMP, to RX_CP_TBL.
|
|
*
|
|
* A flow to perform remained Q/RSS action will be created in RX_ACT_TBL by
|
|
* flow_create_split_metadata() routine. The flow will look like,
|
|
* - If flow ID matches (reg_c[2]), perform Q/RSS.
