+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.
