From 7bdd6f74876e1bf4fc9849fe872000ecc944e71d Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Fri, 17 Oct 2014 03:14:42 +0000 Subject: i40evf: properly handle multiple AQ messages When we receive an admin queue message, the msg_size field in the event struct gets overwritten. Because of this, we need to reinit the field each time we go through the loop. Without this we may receive truncated messages due to the firmware thinking we have insufficient buffer size.
