Subject: [PATCH net-next v2 0/5] enic: Use all the resources configured on
 VIC

Allow users to configure and use more than 8 rx queues and 8 tx queues
on the Cisco VIC.

This series changes the maximum number of tx and rx queues supported
from 8 to the hardware limit of 256, and allocates memory based on the
number of resources configured on the VIC.
