[dpdk-dev] |ERROR| pw 9018 ethdev: add a missing sanity check for nb_tx_desc during txq setup

[Rahul Lakkireddy]

Hi all,

I received this auto email regarding 'Unexpected Packets Drop' and
it is referring to my patch.  I don't think I've changed anything that
could cause this.  Kindly advise.

Thanks,
Rahul
