+Description:
+		Bitmask to allow forwarding of link local frames with address
+		01-80-C2-00-00-0X on a bridge device. Only values that set bits
+		not matching BR_GROUPFWD_RESTRICTED in net/bridge/br_private.h
+		allowed.
+		Default value 0 does not forward any link local frames.
+
+		Restricted bits:
+		0: 01-80-C2-00-00-00 Bridge Group Address used for STP
+		1: 01-80-C2-00-00-01 (MAC Control) 802.3 used for MAC PAUSE
+		2: 01-80-C2-00-00-02 (Link Aggregation) 802.3ad
+
+		Any values not setting these bits can be used. Take special
+		care when forwarding control frames e.g. 802.1X-PAE or LLDP.
