From 755f982bb1ff469a181df3eaf8dd5d769267ab8e Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Sun, 23 Aug 2020 14:19:26 +0300 Subject: qed/qede: make devlink survive recovery Devlink instance lifecycle was linked to qed_dev object, that caused devlink to be recreated on each recovery. Changing it by making higher level driver (qede) responsible for its life. This way devlink now survives recoveries. qede now stores devlink structure pointer as a part of its device object, devlink private data contains a linkage structure, qed_devlink.
