Subject: [PATCH] nfp: fix NFP_NET_MAX_DSCP definition error
References: bsc#1012628
Patch-mainline: 6.3.4
Git-commit: de9c1a23add9e7842ce63ce6f498a05c66344311

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.
