From a925b5e309c9b998658a6a94dbb53154ea901299 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 8 Oct 2020 16:06:37 +0300 Subject: [PATCH] net/mlx5: Register mlx5 devices to auxiliary virtual bus Create auxiliary devices under new virtual bus. This will replace the custom-made mlx5 ->add()/->remove() interfaces and next patches will fill the missing callback and remove the old interface logic. The attachment of auxiliary drivers to the devices is possible in 1-to-1 manner only and it requires us to create device for every protocol, so that device (module) will be able to connect to it.
