> When creating the TLV to send to the FW for configuring DSCP mode PFC,the
> PFCENABLE field was being masked with a 4 bit mask (0xF), but this is an 8 bit
> bitmask for enabled classes for PFC.  This means that traffic classes
> 4-7 could not be enabled for PFC.
> 
> Remove the mask completely, as it is not necessary, as we are assigning 8 bits
> to an 8 bit field.
