I think this could be related to a workaround in glibc local-sysdeps.diff
for kfreebsd:
+ /* FIXME: 'struct if_msghdr' contains a 'struct if_data' which in turns
+ contains 'unsigned long' values. Their size therefore depends on
+ the running kernel (32 or 64 bits). This should be fixed in the
+ compat layer of the kernel. Meanwhile just workaround the bug here/ */
+#if 0
+ sdl = (struct sockaddr_dl *) (msg + 1);
+#else
+ sdl = (struct sockaddr_dl *) (p + msg->ifm_msglen - sizeof(struct sockaddr_dl) - 2);
+#endif
whereas if_data was removed from the struct in the following commit, to
fix the ABI break; that means the workaround should no longer be used?
