ice: Fix DSCP PFC TLV creation
[ Upstream commit fef3f92e8a4214652d8f33f50330dc5a92efbf11 ]
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.
Fixes: 2a87bd73e50d ("ice: Add DSCP support")
