[dpdk-dev] [PATCH v5] app/testpmd: fix testpmd doesn't show RSS hash offload
From: Jie Wang <hidden>
Date: 2021-08-17 09:39:44
Subsystem:
library code, the rest · Maintainers:
Andrew Morton, Linus Torvalds
The driver may change offloads info into dev->data->dev_conf
in dev_configure which may cause port->dev_conf and port->rx_conf
contain outdated values.
This patch updates the offloads info if it changes to fix this issue.
It adds a new API "rte_eth_dev_conf_info_get()" to help testpmd get
device configuration info.
Fixes: ce8d561418d4 ("app/testpmd: add port configuration settings")
