[PATCH mlx5-next 1/2] net/mlx5: Drop redundant esw_cap, reuse e_switch_cap

[Tariq Toukan]

From: Shay Drory <shayd@nvidia.com>

esw_manager_vport_number{,_valid} and merged_eswitch were read through a
separate mlx5_ifc_esw_cap_bits struct, but these bits live in the
e-switch capability that mlx5_ifc_e_switch_cap_bits already describes
(both overlay the same QUERY_HCA_CAP op_mod 0x9 output).

Add esw_manager_vport_number{,_valid} to mlx5_ifc_e_switch_cap_bits at
the same offsets, drop the redundant mlx5_ifc_esw_cap_bits and its
hca_cap_union member, and switch the only user (hws/cmd.c) to
capability.e_switch_cap.

[PATCH mlx5-next 2/2] net/mlx5: ifc: Add PSP related fields

[Tariq Toukan]

From: Cosmin Ratiu <cratiu@nvidia.com>

This adds:
- misc_parameters_6, containing a few fields for matching PSP headers.
As this is the last misc_parameters field defined, retire the old
optimization added in commit [1] to not touch the reserved part.
- PSP decap action.
- PSP SPI header field pointer.

[1] commit 667cb65ae5ad ("net/mlx5: Don't store reserved part in FTEs
and FGs")
