        Regression: No

call setsockopt(fd, SOL_SOCKET, SO_BINDTODEVICE, iface_brlan, iface_len=
 + 1),
the sock's sk_bound_dev_if be set to iface_brlan's index, when i pull o=
ut other
cab and plug in=EF=BC=8C  the br-lan's index can changed, the tcp packe=
t to the socket
be rest, because the orignal sk_bound_dev_if not match current br-lan's=
 index
