The Linux box is logging a standards violation by the other party. As far as it is concerned the other end of the link replied to a packet that went to a broadcast address with an error. This is not permitted (such error replys would generate network storms). On something like ethernet it normally means the other equipment is ancient and buggy, but on non ethernet might just indicate that there are boxes that disagree about the netmask
