The anycast address range is C0:27:C0:27:C0:XX where XX goes from 00 to 1F (or 0 to 31 in dec). The value to write on anycast_mask will specify which addresses the device listens to. Bits in a 32 bit int are numbered from 0 (least significative bit) to 31. A specific address ending in YY will be listened to if bit YY in the value is set to one. Examples: 0x00000000 : do not listen to any anycast address 0xFFFFFFFF : listen to every anycast address from :00 to :1F 0x00000013 : listen to anycast addresses :00, :01 and :04 Signed-off-by: Luis Carlos Cobo Signed-off-by: John W.
