Subject: [PATCH net-next 1/7] ibmvnic: Set real number of rx queues

From: Thomas Falcon <tlfalcon@...ux.vnet.ibm.com>

Along with 5 TX queues, 5 RX queues are allocated at the beginning of
device probe. However, only the real number of TX queues is set. Configure
the real number of RX queues as well.
