Subject: [PATCH net 0/2] ibmvnic: Fix parameter change request handling

When updating parameters for the ibmvnic driver there is a possibility
of entering an infinite loop if a return value other that a partial
success is received from sending the login CRQ.

Also, a deadlock can occur on the rtnl lock if netdev_notify_peers()
is called during driver reset for a parameter change reset.

This patch set corrects both of these issues by updating the return
code handling in ibmvnic_login() nand gaurding against calling
netdev_notify_peers() for parameter change requests.
