From ec95dffa408f0c24c0b358f3723c6ba262190965 Mon Sep 17 00:00:00 2001 From: Nathan Fontenot Date: Wed, 7 Feb 2018 13:00:24 -0600 Subject: [PATCH] ibmvnic: queue reset when CRQ gets closed during reset While handling a driver reset we get a H_CLOSED return trying to send a CRQ event. When this occurs we need to queue up another reset attempt. Without doing this we see instances where the driver is left in a closed state because the reset failed and there is no further attempts to reset the driver.
