Subject: [PATCH] ibmvnic: Fix rx queue cleanup for non-fatal resets
References: bsc#1080014
Patch-mainline: v4.16-rc1
Git-commit: 3468656fd7599b0cb1092bb1ee717d1a984e93ee
At some point, a check was added to exit the polling routine during resets.
This makes sense for most reset conditions, but for a non-fatal error, we
expect the polling routine to continue running to properly clean up the rx
queues. This patch checks if we are performing a non-fatal reset and if we
are, continues normal polling operation.
