Subject: [PATCH net 01/15] ibmvnic: handle inconsistent login with reset

From: Dany Madden <drt@...ux.ibm.com>

Inconsistent login with the vnicserver is causing the device to be
removed. This does not give the device a chance to recover from error
state. This patch schedules a FATAL reset instead to bring the adapter
up.
