Subject: [for-next 10/14] net/mlx5: Add shim layer between fs and cmd
From: Matan Barak <matanb@...lanox.com>
The shim layer allows each namespace to define possibly different
functionality for add/delete/update commands. The shim layer
introduced here, will be used to support flow steering with the FPGA.
