From ee7a711f32a786819f2240290b88c8f5fc0cca96 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Thu, 9 Jan 2020 14:46:18 -0800 Subject: devlink: add parameter documentation for the mlx4 driver The mlx5 and mlxsw drivers have driver-specific documentation for the devlink features they support. No such file was added for mlx4. Add a file to document the mlx4 devlink support. Initially it contains only the devlink parameters.
