[net 01/11] net/mlx5: Imply MLXFW in mlx5_core

[Saeed Mahameed]

mlxfw can be compiled as external module while mlx5_core can be
builtin, in such case mlx5 will act like mlxfw is disabled.

Since mlxfw is just a service library for mlx* drivers,
imply it in mlx5_core to make it always reachable if it was enabled.

[net 02/11] net/mlx5: Add meaningful return codes to status_to_err function

[Saeed Mahameed]

From: Valentine Fatiev <valentinef@mellanox.com>

Current version of function status_to_err return -1 for any
status returned by mlx5_cmd_invoke function. In case status is
MLX5_DRIVER_STATUS_ABORTED we should return 0 to the caller as we
assume command completed successfully on FW. If error returned we are
getting confusing messages in dmesg. In addition, currently returned
value -1 is confusing with -EPERM.

New implementation actually fix original commit and return meaningful
codes for commands delivery status and print message in case of failure.

[net 03/11] net/mlx5: E-Switch, Correct type to u16 for vport_num and int for vport_index

[Saeed Mahameed]

From: Parav Pandit <parav@mellanox.com>

To avoid any ambiguity between vport index and vport number,
rename functions that had vport, to vport_num or vport_index appropriately.

vport_num is u16 hence change mlx5_eswitch_index_to_vport_num() return
type to u16.

vport_index is an int in vport array. Hence change input type of vport
index in mlx5_eswitch_index_to_vport_num() to int.

Correct multiple eswitch representor interfaces use type u16 of
rep->vport as type int vport_index.

Send vport FW commands with correct eswitch u16 vport_num instead
host int vport_index.

[net 06/11] net/mlx5e: Fix ethtool rxfh commands when CONFIG_MLX5_EN_RXNFC is disabled

[Saeed Mahameed]

ethtool user spaces needs to know ring count via ETHTOOL_GRXRINGS when
executing (ethtool -x) which is retrieved via ethtool get_rxnfc callback,
in mlx5 this callback is disabled when CONFIG_MLX5_EN_RXNFC=n.

This patch allows only ETHTOOL_GRXRINGS command on mlx5e_get_rxnfc() when
CONFIG_MLX5_EN_RXNFC is disabled, so ethtool -x will continue working.

[net 09/11] net/mlx5e: Additional check for flow destination comparison

[Saeed Mahameed]

From: Dmytro Linkin <dmitrolin@mellanox.com>

Flow destination comparison has an inaccuracy: code see no
difference between same vf ports, which belong to different pfs.

Example: If start ping from VF0 (PF1) to VF1 (PF1) and mirror
all traffic to VF0 (PF2), icmp reply to VF0 (PF1) and mirrored
flow to VF0 (PF2) would be determined as same destination. It lead
to creating flow handler with rule nodes, which not added to node
tree. When later driver try to delete this flow rules we got
kernel crash.

Add comparison of vhca_id field to avoid this.

[net 11/11] net/mlx5e: Fix possible modify header actions memory leak

[Saeed Mahameed]

From: Eli Britstein <elibr@mellanox.com>

The cited commit could disable the modify header flag, but did not free
the allocated memory for the modify header actions. Fix it.

Fixes: 27c11b6b844cd ("net/mlx5e: Do not rewrite fields with the same match")
