Subject: RDMA/irdma: Refactor DCB bits in prep for DSCP support
Patch-mainline: v5.18-rc1
Git-commit: 83483055321f1e5e45abc1444c49d916e1c52bc4
References: jsc#PED-377
Rename dcb flag to dcb_vlan_mode in irdma_device struct. Add a new helper
function, irdma_set_qos_info, to set the VSI QoS information passed by the
PCI driver.
