Subject: ethdev: fix checking Rx/Tx queue status
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b447e89e33336324e7b4729cd35b5a017fe5dd82;p=dpdk.git

ethdev: fix checking Rx/Tx queue status

Relax the check for queue setup, since some device
may not update queue states during dev_stop.

Fixes: cac923cfea47 ("ethdev: support runtime queue setup")
