Hi facoptere, this is intentional behavior to allow broadcast packets on
sockets that are "bound" to a specific interface (broadcast packets only work
when binding to 0.0.0.0).  The new code will set a kernel option (not available
on old kernels) that sets the packet to go out through the interface associated
with the specified address.  There's also a packet filter to only accept
packets that come in through (or are destined for) the provided address.  Could
you give more detail on the specific problem you are running into?
