[dpdk-dev,1/8] bond: use existing enslaved device queues
Commit Message
From: Eric Kinzie <ehkinzie@gmail.com>
This solves issues when an active device is added to a bond.
If a device to be enslaved already has transmit and/or receive queues
allocated, use those and then create any additional queues that are
necessary.
