  If a initial process for the bonding device is like:
rte_eth_dev_configure
rte_eth_dev_set_mtu
queue setup and start, etc.

Pass the vdev args to application, and init bonding device only.
-a 0000:af:00.0 --vdev="net_bonding0,mode=2,slave=0000:af:00.0"

It will fail and compain for the slave device
"Port 0 must be configured before MTU set"

Test can be reproduced with ovs.

Fixes: b26bee1 ("ethdev: forbid MTU set before device configure")

Change looks good to me, previously configure(), queue setup & start()
all done in .dev_start dev_ops.

Now configure part separated and .dev_configure also calls the configure
part, .dev_start still does the same.

Conner, Chas, if there is no objection from you, I will proceed with
the patch and merge it soon.
