	May be because there is a bug in all kernels. Wensong provided
patch to the maintainers. IP_MULTICAST_IF binds to interface but
it is saved in another place (sk->ip_mc_index). udp_connect() and
udp_sendmsg() behave differently. Of course, you can explicitly
bind to device with SO_BINDTODEVICE as I see it in the following
paragraph. In any case, I don't know what you consider as a bad
behavior (which syscall) - why do you need valid data in bound_dev_if?
