From: Saeed Mahameed <saeedm@nvidia.com>

Hi Dave, Hi Jakub,

This series adds 2 main changes to mlx5
1) New Devlink knobs to control EQ sizes, already acked by Jiri and
Jakub. first 6 commits.

Link: https://lore.kernel.org/netdev/20211208141722.13646-1-shayd@nvidia.com/

2) Memory optimization of netdev's channels data.

For more information please see tag log below.

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

Thanks,
Saeed.

  net/mlx5e: Take packet_merge params directly from the RX res struct (2021-12-21 19:08:58 -0800)

----------------------------------------------------------------
mlx5-updates-2021-12-21

1) From Shay Drory: Devlink user knobs to control device's EQ size

This series provides knobs which will enable users to
minimize memory consumption of mlx5 Functions (PF/VF/SF).
mlx5 exposes two new generic devlink params for EQ size
configuration and uses devlink generic param max_macs.

2) From Tariq and Lama, allocate software channel objects and statistics
  of a mlx5 netdevice private data dynamically upon first demand to save on
  memory.

----------------------------------------------------------------
Lama Kayal (1):
      net/mlx5e: Allocate per-channel stats dynamically at first usage

Shaokun Zhang (1):
      net/mlx5: Remove the repeated declaration

Shay Drory (6):
      devlink: Add new "io_eq_size" generic device param
      net/mlx5: Let user configure io_eq_size param
      devlink: Add new "event_eq_size" generic device param
      net/mlx5: Let user configure event_eq_size param
      devlink: Clarifies max_macs generic devlink param
      net/mlx5: Let user configure max_macs generic param

Tariq Toukan (6):
      net/mlx5e: Use bitmap field for profile features
      net/mlx5e: Add profile indications for PTP and QOS HTB features
      net/mlx5e: Save memory by using dynamic allocation in netdev priv
      net/mlx5e: Allow profile-specific limitation on max num of channels
      net/mlx5e: Use dynamic per-channel allocations in stats
      net/mlx5e: Take packet_merge params directly from the RX res struct
