This is for the case device configuration get, a few thing changed and re-configured case, this is what is done in bonding and it is failing now. Do you have any suggestion for the solution? We can set this offload in PMDs only if 'ETH_MQ_RX_RSS_FLAG' set but same thing still can caught us, if the initial configuration was with 'ETH_MQ_RX_RSS_FLAG' but reconfigure is not. Or we can relax the check in 'rte_eth_dev_configure()' to log but not return error?
