'rxmode.mq_mode' is an enum which should be an abstraction over values,
instead of mask it with 'RTE_ETH_MQ_RX_RSS_FLAG' to detect if RSS is
supported, directly compare with 'RTE_ETH_MQ_RX_RSS' enum element.
Most of the time only 'RTE_ETH_MQ_RX_RSS' is requested by user, that is
why output is almost same, but there may be cases driver doesn't support
RSS combinations, like 'RTE_ETH_MQ_RX_VMDQ_DCB_RSS' but that is hidden
by masking with 'RTE_ETH_MQ_RX_RSS_FLAG'.
Fixes: 73fb89dd6a00 ("drivers/net: fix RSS hash offload flag if no RSS")

There are more usage like "rxmode->mq_mode & RTE_ETH_MQ_RX_RSS_FLAG" in
drivers, not sure to fix all in this commit or not, feedback welcomed.

Hi Ferruh, It seems that this fully changes the usage of the mq_mode. It will cause RSS, DCB and VMDQ function cannot work well. For example, Both user and driver enable RSS and DCB functions based on xxx_DCB_FLAG and xxx_RSS_FLAG in rxmode.mq_mode. If we directly compare with 'RTE_ETH_MQ_RX_RSS' enum element now, how do we enable RSS+DCB mode? /Huisong > > Fixes: 73fb89dd6a00 ("drivers/net: fix RSS hash offload flag if no RSS") > Cc: stable@dpdk.org > > Signed-off-by: Ferruh Yigit <ferruh.yigit@amd.com> > > --- > > There are more usage like "rxmode->mq_mode & RTE_ETH_MQ_RX_RSS_FLAG" in > drivers, not sure to fix all in this commit or not, feedback welcomed. > --- > drivers/net/bnxt/bnxt_ethdev.c | 2 +- > drivers/net/cxgbe/cxgbe_ethdev.c | 2 +- > drivers/net/e1000/igb_ethdev.c | 4 ++-- > drivers/net/ena/ena_ethdev.c | 2 +- > drivers/net/enic/enic_ethdev.c | 2 +- > drivers/net/fm10k/fm10k_ethdev.c | 2 +- > drivers/net/gve/gve_ethdev.c | 2 +- > drivers/net/hinic/hinic_pmd_ethdev.c | 2 +- > drivers/net/hns3/hns3_ethdev.c | 2 +- > drivers/net/hns3/hns3_ethdev_vf.c | 2 +- > drivers/net/i40e/i40e_ethdev.c | 2 +- > drivers/net/iavf/iavf_ethdev.c | 2 +- > drivers/net/ice/ice_dcf_ethdev.c | 2 +- > drivers/net/ice/ice_ethdev.c | 2 +- > drivers/net/igc/igc_ethdev.c | 2 +- > drivers/net/ixgbe/ixgbe_ethdev.c | 4 ++-- > drivers/net/liquidio/lio_ethdev.c | 2 +- > drivers/net/mana/mana.c | 2 +- > drivers/net/netvsc/hn_ethdev.c | 2 +- > drivers/net/nfp/nfp_common.c | 2 +- > drivers/net/ngbe/ngbe_ethdev.c | 2 +- > drivers/net/qede/qede_ethdev.c | 2 +- > drivers/net/thunderx/nicvf_ethdev.c | 2 +- > drivers/net/txgbe/txgbe_ethdev.c | 2 +- > drivers/net/txgbe/txgbe_ethdev_vf.c | 2 +- > drivers/net/vmxnet3/vmxnet3_ethdev.c | 2 +- > 26 files changed, 28 insertions(+), 28 deletions(-) > > diff --git a/drivers/net/bnxt/bnxt_ethdev.c b/drivers/net/bnxt/bnxt_ethdev.c > index 753e86b4b2af..14c0d5f8c72b 100644 > --- a/drivers/net/bnxt/bnxt_ethdev.c > +++ b/drivers/net/bnxt/bnxt_ethdev.c > @@ -1143,7 +1143,7 @@ static int bnxt_dev_configure_op(struct rte_eth_dev *eth_dev) > bp->rx_cp_nr_rings = bp->rx_nr_rings;

Overall I think it is not good idea to use enum items as masked values, but that seems done intentionally in the past: Commit 4bdefaade6d1 ("ethdev: VMDQ enhancements") Since this can be in use already, following patch only changes where 'RTE_ETH_RX_OFFLOAD_RSS_HASH' is set, rest of the usage remaining same. And even for 'RTE_ETH_RX_OFFLOAD_RSS_HASH', I think intention was to override this offload config in PMD when explicitly RSS mode is enabled, but I made the set as RFC to get feedback on this. We may keep as it is if some other modes with 'RTE_ETH_MQ_RX_RSS_FLAG' uses this offload. >> >> Fixes: 73fb89dd6a00 ("drivers/net: fix RSS hash offload flag if no RSS") >> Cc: stable@dpdk.org >> >> Signed-off-by: Ferruh Yigit <ferruh.yigit@amd.com> >> >> --- >> >> There are more usage like "rxmode->mq_mode & RTE_ETH_MQ_RX_RSS_FLAG" in >> drivers, not sure to fix all in this commit or not, feedback welcomed. >> --- >> drivers/net/bnxt/bnxt_ethdev.c | 2 +- >> drivers/net/cxgbe/cxgbe_ethdev.c | 2 +- >> drivers/net/e1000/igb_ethdev.c | 4 ++-- >> drivers/net/ena/ena_ethdev.c | 2 +- >> drivers/net/enic/enic_ethdev.c | 2 +- >> drivers/net/fm10k/fm10k_ethdev.c | 2 +- >> drivers/net/gve/gve_ethdev.c | 2 +- >> drivers/net/hinic/hinic_pmd_ethdev.c | 2 +- >> drivers/net/hns3/hns3_ethdev.c | 2 +- >> drivers/net/hns3/hns3_ethdev_vf.c | 2 +- >> drivers/net/i40e/i40e_ethdev.c | 2 +- >> drivers/net/iavf/iavf_ethdev.c | 2 +- >> drivers/net/ice/ice_dcf_ethdev.c | 2 +- >> drivers/net/ice/ice_ethdev.c | 2 +- >> drivers/net/igc/igc_ethdev.c | 2 +- >> drivers/net/ixgbe/ixgbe_ethdev.c | 4 ++-- >> drivers/net/liquidio/lio_ethdev.c | 2 +- >> drivers/net/mana/mana.c | 2 +- >> drivers/net/netvsc/hn_ethdev.c | 2 +- >> drivers/net/nfp/nfp_common.c | 2 +- >> drivers/net/ngbe/ngbe_ethdev.c | 2 +- >> drivers/net/qede/qede_ethdev.c | 2 +- >> drivers/net/thunderx/nicvf_ethdev.c | 2 +- >> drivers/net/txgbe/txgbe_ethdev.c | 2 +- >> drivers/net/txgbe/txgbe_ethdev_vf.c | 2 +- >> drivers/net/vmxnet3/vmxnet3_ethdev.c | 2 +- >> 26 files changed, 28 insertions(+), 28 deletions(-) >> >> diff --git a/drivers/net/bnxt/bnxt_ethdev.c >> b/drivers/net/bnxt/bnxt_ethdev.c >> index 753e86b4b2af..14c0d5f8c72b 100644 >> --- a/drivers/net/bnxt/bnxt_ethdev.c >> +++ b/drivers/net/bnxt/bnxt_ethdev.c >> @@ -1143,7 +1143,7 @@ static int bnxt_dev_configure_op(struct >> rte_eth_dev *eth_dev) >> bp->rx_cp_nr_rings = bp->rx_nr_rings;

This is not a good way to use.

It is better to change rxmode.mq_mode and txmode.mq_mode type from 'enum' to 'u32'. In this way, PMD code logic don't need to be modified and the impact on PMDs and user is minimal.

If bitmask feature of mq_mode is used and needed, I agree changing underlying data type cause less disturbance in logic.
