[pull request][net-next 00/11] Mellanox, mlx5 updates 2019-02-19

[Saeed Mahameed]

Hi Dave,

This series provides some updates to mlx5 driver.
In addition, there is one patch that defines new 50Gbps per lane link
modes in include/uapi/linux/ethtool.h:
("ethtool: Added support for 50Gbps per lane link modes")

For more information please see tag log below.

Please pull and let me know if there is any problem.

Thanks,
Saeed.

[net-next 02/11] net/mlx5: ethtool, Add ethtool support for 50Gbps per lane link modes

[Saeed Mahameed]

From: Aya Levin <ayal@mellanox.com>

In previous patch, driver added new speed modes: 50Gbps per lane support
for 50G/100G/200G.  This patch modifies mlx5e_get_link_ksettings and
mlx5e_set_link_ksettings to set and get these link modes via ethtool.
In order to do so, added mapping of new HW bits to ethtool bitmap and
enforce mutual exclusion between extended link modes and previously
defined link modes.

[net-next 03/11] net/mlx5e: Wrap the open and apply of channels in one fail-safe function

[Saeed Mahameed]

From: Tariq Toukan <tariqt@mellanox.com>

Take into a function the common code structure of opening
a side set of channels followed by a call to apply them.

[net-next 04/11] net/mlx5e: Remove wrong and superfluous tc pedit header type check

[Saeed Mahameed]

From: Vlad Buslov <vladbu@mellanox.com>

With recent introduction of flow_rule infrastructure drivers no longer
directly include action headers, so it is no longer possible to use
constants defined in them. Instead, one of flow_rule patches substituted
pedit action header constant with hardcoded value '2' in mlx5
set_pedit_val() function conditional which verifies that header type is in
range of values allowed by pedit action. That conditional is now both
wrong (hardcoded value is '2' but __PEDIT_HDR_TYPE_MAX is 6 in current
version) and superfluous (pedit action already verifies that header type is
in allowed range during init). Remove the described check from mlx5 code.
