From ff2ff3b45eba19ce87dda2ee577201ea733f24e2 Mon Sep 17 00:00:00 2001 From: Shannon Nelson <shannon.nelson@intel.com> Date: Wed, 18 Dec 2013 13:45:56 +0000 Subject: [PATCH] i40e: release NVM resource reservation on startup Call AQ to release any reservation held by this PF on the NVM resource lock on startup, in order to clear anything that might have been left over from a previous run. The lock is only cleared by the requestor calling for it to be cleared, on power-on, or firmware reset. This should help limit the need for rebooting a customer machine if something goes wrong on a firmware update or some other action.
