Re: Was change to ip_push_pending_frames intended to break udp (more specifically, WCCP?)

IP id is set to 0 on unconnected sockets when the DF bit is set (path
mtu discovery is enabled).  Try issuing a connect() in your application
and see if the ids are increasing again.

ID of zero again? I thought that went away years ago? Anyway, given the number of "helpful" devices out there willing to clear the DF bit, fragment and forward, perhaps always setting the IP ID to 0, even if DF is set, isn't such a good idea?
