From: Huayu Chen <huayu.chen@xxxxxxxxxxxx>
commit de9c1a23add9e7842ce63ce6f498a05c66344311 upstream.
The patch corrects the NFP_NET_MAX_DSCP definition in the main.h file.
The incorrect definition result DSCP bits not being mapped properly when
DCB is set. When NFP_NET_MAX_DSCP was defined as 4, the next 60 DSCP
bits failed to be set.
Fixes: 9b7fe8046d74 ("nfp: add DCB IEEE support")
