Richard Cochran 347b42b7d5 udp: Use the bind to device socket option.
Without this Linux specific option, multicast packets arrive on one
interface are delivered by the kernel to all others.

This option is on by default, but we don't want or need it.

Richard Cochran 5555a2f029 udp: Use the IP_ADD_MEMBERSHIP socket option.
For some reason, MCAST_JOIN_GROUP is not working under uClinux. We can
just stick with the more traditional method.

Richard Cochran cecc20a307 udp: wait longer for transmit time stamps
Some hardware is a bit pokey. We now wait forever on EINTR and just a
little bit on EAGAIN.

Richard Cochran 5f7facdc63 Bind transmitted packets to the port's network interface.
Even though the MCAST_JOIN_GROUP socket option includes the interface
index, this applies to the received packets only. To bind the outgoing
packets to a particular interface, the IP_MULTICAST_IF option is needed.
