[dpdk-dev] Drops seen with virtio pmd driver

[Venumadhav Josyula]

Hi All,

We are observing packet drops ~@90Mbs with virtio pmd driver. These packets
are not been
queued in the tx descriptors, the function 'rte_eth_tx_burst' is returning
the less than n.

So questions are following
i)  are there any issues seen ?

Observations in our case :-
i) packets are dropped and tx packets donot get incremented.
ii) i) happens for 30 secs after that it recovers.
iii) After sometime we see this issue in i) & ii) again.

Any clues / pointers will help.

Thanks,
Regards,
Venu
