[dpdk-dev] [PATCH 1/4] net/hns3: modify the statistics for sending and receiving messages
Wei Hu (Xavier)
xavier.huwei at tom.com
Wed Oct 9 16:16:50 CEST 2019
From: Hao Chen <chenhao164 at huawei.com>
In receiving direction, for FCS error messages, drivers no longer
record them in rte_eth_stats.ipackets statistics.
In sending direction, for messages of illegal length, too long or
equals 0, drivers will not notify the network card hardware to
send them, will not continue to send the remaining message in burst,
and will not record them in rte_eth_stats.opackets statistics.
