From 77813d0a9f750f8d5075bcbb59d30417e51ab605 Mon Sep 17 00:00:00 2001 From: Kamil Krawczyk Date: Wed, 9 Jul 2014 07:46:15 +0000 Subject: [PATCH] i40e/i40evf: ARQ copy desc data even for failed commands Copy desc and buffer data even for ARQ events which return error status. Previously, a check for NVM related AQ commands which is done later in this function would not recognize that such a command was received and would not clear nvm_busy flag. This would block access to NVM until a driver reset. This will fix that.
