[dpdk-stable] [PATCH] net/iavf: fix queue start failed

[Qiming Chen]

In the iavf_dev_start function, if the first execution of
iavf_start_queues fails, it will still fail when it is started again.
The patch solves the problem of rolling back resources after the queue
fails to start, and then restarts successfully.

Fixes: 69dd4c3d0898 ("net/avf: enable queue and device")
