[PATCH mlx5-next 0/4] Add support to multiple RDMA priorities for FDB rules

[PATCH mlx5-next 0/4] Add support to multiple RDMA priorities for FDB rules

[Saeed Mahameed]

From: Saeed Mahameed <saeedm@nvidia.com>

Currently, the driver ignores the user's priority for flow steering
rules in FDB namespace. Change it and create the rule in the right
priority.

It will allow to create FDB steering rules in up to 16 different
priorities.

Maor Gottlieb (4):
  net/mlx5: Separate FDB namespace
  net/mlx5: Refactor mlx5_get_flow_namespace
  net/mlx5: Create more priorities for FDB bypass namespace
  RDMA/mlx5: Add support to multiple priorities for FDB rules

[PATCH mlx5-next 1/4] net/mlx5: Separate FDB namespace

[Saeed Mahameed]

From: Maor Gottlieb <maorg@nvidia.com>

This patch doesn't add an additional namespaces, but just separates the
naming to be used by each FDB user, bypass and kernel.
Downstream patches will actually split this up and allow to have more
than single priority for the bypass users.
