ixgbevf: Set the netdev number of Tx queues
The driver was not setting the number of real Tx queues in the net_device
structure. This caused some serious issues such as Tx hangs and extremely
poor performance with some usages of the driver.
The issue is best observed by running:
iperf -c <host> -P <n>
Where n is greater than one. The greater the value of n the more likely
the problem is to show up.
