From: Dekel Peled <dekelp@mellanox.com>
[ upstream commit 70faf9ae0a299e5750b687dfecb6efc65b038304 ]
According to PRM: "Drop action is mutually-exclusive with any other
action, except for Count action".
In current code this limitation is checked separately in validation
function of each action.
This patch removes the discrete checks, and adds a single check common
for all actions.

The id allocated is for the register unique id match. Some registers may
not use the full 32 bits. Add the maximum id to avoid allocate id over
the register restriction.

[ upstream commit 792e749e92d585ed083c80ab5c15cf5203534ae9 ]
Flow with meter will split to three subflows, the prefix subflow with
meter action do the color, the meter subflow filter the packets, the
suffix subflow do all the left actions for packets pass the filter.
Both the color and the subflow match between prefix and suffix use the
register to store the tag.
For some of the NICs with meter color register share capability, it
only uses 8 LSB of the register for color, the left 24 MSB can be used
for flow id match between meter prefix subflow and suffix subflow.
Currently, one entire register is allocated for flow matching which
causes the NICs with limited registers don't have enough register for
other matching.
Add the meter color share capability checking to fix lacking of
registers issue.
Fixes: 9ea9b049a960 ("net/mlx5: split meter flow")

From: Matan Azrad <matan@mellanox.com>
[ upstream commit 06387be8eae5755e5b9952cd9d5d84ba0e5ad6b5 ]
The encapsulation and decapsulation actions are divided into 2 types:
L2 and L3.
In order to configure L3 xcapsulation actions the user should use both
RAW_DECAP and RAW_ENCAP and setting the appropriated data sizes in
their action configuration structures.
The PMD flow validation wrongly didn't detect the RAW_DECAP
and RAW_ENCAP combination to distinguish between L3_DECAP and L3_ENCAP.
Thus, some xcapsulation related validation failed.
For example, when configuring modify header action before L3_DECAP.
Simplify the xcapsulation defines and fix the L3 xcapsulation detection
using the action configuration data sizes.
By the way, add the hairpin validation in this area.
Fixes: d85c7b5ea59f ("net/mlx5: split hairpin flows")
Fixes: 8ba9eee4ce32 ("net/mlx5: add raw data encap/decap to Direct Verbs")

[ upstream commit e505ac7f91b59e1165c143f14b208885658d2f94 ]
Currently, the flow validate function only validate the outermost layer
with the header modify actions. If there is decapsulation action before
the header modify action, the validation should choose the inner layer
for validation.
Add decapsulation check when validate with the header modify actions.
Choose the inner layer once there is decapsulation action.

[ upstream commit 04233f36c712ea35fe0f1d02c5c6f323a28ec588 ]
Currently, for header modify actions after tunnel decapsulation, the
header modify actions will still select the old outermost layer type.
It will cause header modify actions get the wrong layer type.
Add the tunnel decap flag to indicate the layer type to get for header
modify actions.

[ upstream commit bc42413bb9c0b767e40c5a52e529277c06608a3b ]
Metadata suffix subflow inherits the RSS needed hash_fields from the
prefix subflow as the suffix subflow only has the tag match item unable
to generate the full original hash_fields for RSS action.
Unfortunately, hash_fields will only be generated if flow has RSS
action. So it means the prefix flow won't generate the hash_fields as
the RSS action has been split to the suffix flow.
Copy the layer flags from prefix subflow to suffix subflow to help the
suffix subflow to generate the correct hash_fields itself.

[ upstream commit 6e77151286b2f551ae30aac0f251ed067f1ec011 ]
As meter flows are split into three subflows each, the prefix subflow
with meter action color the packet, the meter subflow filters out the
colored packets, the suffix subflow applies all the remaining actions
to the passed packets.
Currently, all the user defined items are matched in the prefix flow.
Flow id tag match item is the only item added to the meter suffix
subflow. Some of the remaining actions to be applied in the suffix
subflow require more information in the match item, or the suffix
subflow will not be created successfully.
Actions require the L3/L4 type in the match items as below:
RTE_FLOW_ACTION_TYPE_SET_TP_SRC
RTE_FLOW_ACTION_TYPE_SET_TP_DST
RTE_FLOW_ACTION_TYPE_DEC_TTL
RTE_FLOW_ACTION_TYPE_SET_TTL
RTE_FLOW_ACTION_TYPE_RSS
RTE_FLOW_ACTION_TYPE_QUEUE
Inherit the match item flags from meter prefix subflow to make actions
in suffix subflow get sufficient information.

[ upstream commit 50f576d657d78e87a3eac597353d236969969c17 ]
Meter suffix subflow only has the port id and tag match item, if VLAN
push and set VLAN id actions exist in the suffix subflow, the user
defined VLAN items is required for the actions to set a correct VLAN
id.
Currently, the VLAN item stays in the meter prefix subflow. Without
the VLAN item, VLAN id or pcp will not be inherited.
Actions require the VLAN item as below:
RTE_FLOW_ACTION_TYPE_OF_PUSH_VLAN
RTE_FLOW_ACTION_TYPE_OF_SET_VLAN_VID
Add a private VLAN item to copy the user defined VLAN item to the meter
suffix subflow, so the suffix subflow will have the chance to get the
correct original VLAN id and pcp value from the VLAN item.

From: Matan Azrad <matan@mellanox.com>
[ upstream commit 35594a9b6f96ac6e45bbb851d9180c841c35cfff ]
In order to move the mbuf metadata from the WQE to the FDB steering
domain, the PMD add for each NIC TX flow a new action to copy the
metadata register REG_A to REG_C_0.
This copy action is considered as modify header action from HW
perspective.
The HW doesn't support to do modify header action after ant
encapsulation action.
The split metadata function wrongly added the copy action in the end of
the original actions list, hence, NIC egress flow with encapsulation
action failed when the PMD worked with dv_xmeta_en mode.
Move the copy action to be before and back to back with the
encapsulation action for the aforementioned case.
Fixes: 71e254bc0294 ("net/mlx5: split Rx flows to provide metadata copy")

Thank you, applied. I also dropped the previous version of "net/mlx5:
fix metadata split with encap action" in favour of yours.
