From bd032e35c568ff7cfa347aa4ddd6491e2453f00c Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Tue, 12 Oct 2021 16:15:24 +0300 Subject: devlink: Allow control devlink ops behavior through feature mask Introduce new devlink call to set feature mask to control devlink behavior during device initialization phase after devlink_alloc() is already called. This allows us to set reload ops based on device property which is not known at the beginning of driver initialization. For the sake of simplicity, this API lacks any type of locking and needs to be called before devlink_register() to make sure that no parallel access to the ops is possible at this stage.
