> 	ixgbe: fix multi-process support
> When start primary process with command line:

> then start the second one:
> ./app/test/test -n 1 --proc-type=3Dsecondary --file-prefix=3Drte
> This segment-fault will occur.

> Root cause is test app on primary process only starts device, but
> the queue need initialized by manually command line.
> So the tx queue is still NULL when secondary process startup.
