[net-next 02/17] net/mlx5e: Move code chunk setting encap dests into its own function

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

Split setting encap dests code chunk out of mlx5e_tc_add_fdb_flow()
to make the function smaller for maintainability and reuse.
For symmetry do the same for mlx5e_tc_del_fdb_flow().
While at it refactor cleanup to first check for encap flag like
done when setting encap dests.

[net-next 03/17] net/mlx5e: Pass attr arg for attaching/detaching encaps

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

In later commit that we will have multiple attr instances per flow
we would like to pass a specific attr instance to set encaps.

Currently the mlx5_flow object contains a single mlx5_attr instance.
However, multi table actions (e.g. CT) instantiate multiple attr instances.

Currently mlx5e_attach/detach_encap() reads the first attr instance
from the flow instance. Modify the functions to receive the attr
instance as a parameter which is set by the calling function.

[net-next 05/17] net/mlx5e: TC, Move pedit_headers_action to parse_attr

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

Move pedit_headers_action from flow parse_state to flow parse_attr.
In a follow up commit we are going to have multiple attr per flow
and pedit_headers_action are unique per attr.

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

In later commit we are going to instantiate multiple attr instances
for flow instead of single attr.
Make sure the parsing using correct attr and not flow->attr.

[net-next 08/17] net/mlx5e: TC, Refactor mlx5e_tc_add_flow_mod_hdr() to get flow attr

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

In later commit we are going to instantiate multiple attr instances
for flow instead of single attr.
Make sure mlx5e_tc_add_flow_mod_hdr() use the correct attr and not flow->attr.

[net-next 09/17] net/mlx5e: TC, Reject rules with multiple CT actions

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

The driver doesn't support multiple CT actions.
Multiple CT clear actions are ok as they are redundant also with
another CT actions.

[net-next 10/17] net/mlx5e: TC, Hold sample_attr on stack instead of pointer

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

In later commit we are going to instantiate multiple attr instances
for flow instead of single attr.
Parsing TC sample allocates a new memory but there is no symmetric
cleanup in the infrastructure.
To avoid asymmetric alloc/free use sample_attr as part of the flow attr
and not allocated and held as a pointer.
This will avoid a cleanup leak when sample action is not on the first
attr.

[net-next 11/17] net/mlx5e: CT, Don't set flow flag CT for ct clear flow

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

ct clear action is a normal flow with a modify header for registers to
0. there is no need for any special handling in tc_ct.c.
Parsing of ct clear action still allocates mod acts to set 0 on the
registers and the driver continue to add a normal rule with modify hdr
context.

[net-next 13/17] net/mlx5e: Test CT and SAMPLE on flow attr

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

Currently the mlx5_flow object contains a single mlx5_attr instance.
However, multi table actions (e.g. CT) instantiate multiple attr instances.
Prepare for multiple attr instances by testing for CT or SAMPLE flag on attr
flags instead of flow flag.

[net-next 14/17] net/mlx5e: TC, Store mapped tunnel id on flow attr

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

In preparation for multiple attr instances the tunnel_id should
be attr specific and not flow specific.

[net-next 16/17] net/mlx5: Introduce software defined steering capabilities

[Saeed Mahameed]

From: Dima Chumak <dchumak@nvidia.com>

There are two different internal steering modes, abstracted from the
rest of the driver. In order to keep upper layer of the driver agnostic
to the differences in capabilities of the steering modes, this patch
introduces mlx5_fs_get_capabilities() API to check if a certain software
defined capability is supported. It differs from the capabilities
exposed by the hardware, as it takes into account the flow steering mode
(SMFS/DMFS) currently enabled.

This implementation supports only two capability flags:

  MLX5_FLOW_STEERING_CAP_VLAN_PUSH_ON_RX
  MLX5_FLOW_STEERING_CAP_VLAN_POP_ON_TX

They map to DR_ACTION_STATE_PUSH_VLAN and DR_ACTION_STATE_POP_VLAN
actions, implemented in SW steering earlier in commit f5e22be534e0
("net/mlx5: DR, Split modify VLAN state to separate pop/push states").
Which enables using of pop/push vlan without restrictions, e.g. doing
vlan pop on TX and RX, compared to FW steering that supports only vlan
pop on RX and push on TX.

Other capabilities can be added in the future.

[net-next 17/17] net/mlx5: VLAN push on RX, pop on TX

[Saeed Mahameed]

From: Dima Chumak <dchumak@nvidia.com>

Some older NIC hardware isn't capable of doing VLAN push on RX and pop
on TX.

A workaround has been added in software to support it, but it has a
performance penalty since it requires a hairpin + loopback.

There's no such limitation with the newer NICs, so no need to pay the
price of the w/a. With this change the software w/a is disabled for
certain HW versions and steering modes that support it.
