From bf06f7a9bafde62fa77e3fce4040355dfbceb894 Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Thu, 13 Nov 2014 08:23:14 +0000 Subject: [PATCH] i40e: let firmware catch the NVM busy error The NVM update operations take time finish asynchronously, and follow-on update requests need to wait for the current one to finish. Early firmware didn't handle this well, so the code had to track the busy state. The released firmware handles the busy state correctly, returning I40E_AQ_RC_EBUSY if an update is still in progress, so the code no longer needs to track this.
