> 
> The patch that implemented DSCP QoS implementation removed a bandwidth
> check that was used to check for a specific condition caused by some corner
> cases.  This check should not of been removed.
> 
> The same patch also added a check for when the DCBx state could be changed
> in relation to DSCP, but the check was erroneously added nested in a check for
> CEE mode, which made the check useless.
> 
> Fix these problems by re-adding the bandwidth check and relocating the DSCP
> mode check earlier in the function that changes DCBx state in the driver.

> Fixes: 2a87bd73e5 ("ice: Add DSCP support")
