[dpdk-dev] [PATCH v2 6/9] net/kni: do not count unsent packets as errors

[David Marchand]

err_pkts reflects the number of packets that the driver did not manage to
send.
This is a temporary situation, those packets are not freed and the
application can still retry to send them later.
Hence, we can't count them as transmit failed.

Fixes: 75e2bc54c018 ("net/kni: add KNI PMD")

Changelog since v1:
- dropped the err_pkts counter entirely as nothing reports it
