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outdated values.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.

Hi Jie,

ci/intel-Testing is still reporting some errors [1] with this patch, did you able to
investigate the reason of it?

This error seems not seen in other patches, so that shouldn't be an infrastructure
problem.

Hi Ferruh,

When the dpdk runs the test_pf_tx_rx_queue test case, the port will be configured with rxq/txq to 1. This will cause the test to fail.

In rte_eth_dev_configure, if rxq/txq is 1, dev_conf->rxmode.mq_mode is ETH_MQ_RX_NONE, and  dev_conf->rxmode.offloads contains the DEV_RX_OFFLOAD_RSS_HASH value by default, which causes the program to report an error " Ethdev port_id=0 config invalid Rx mq_mode without RSS but RSS_HASH offload is requested".

When the port needs to configure txq/txq to 1, first clear the RSS_HASH configuration of dev_conf->rxmode.offloads.

And I have talked about this error with the tester a few days ago, and they will modify the test case. They will add a command (port config port_id rx_offload rss_hash off) before configuring txq/rxq to 1.
