[v5] app/testpmd: fix testpmd doesn't show RSS hash offload
Checks
Commit Message
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contain outdated values.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.

Comments
Launch testpmd with multiple queues, and check rx_offload info.
When testpmd shows the port configuration, it doesn't show RSS_HASH.
---
v6: split this patch into two patches.
v5: add an API to get device configuration info.
v4: delete the whitespace at the end of the line.
v3:
- check and update the "offloads" of "port->dev_conf.rx/txmode".
- update the commit log.
v2: copy "rx/txmode.offloads", instead of copying the entire struct
"dev->data->dev_conf.rx/txmode".
