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. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2012-01-07 08:07:54 +01:00
Richard Cochran	95d5c36c0f	udp: turn off multicast loop back. This option is on by default, but we don't want or need it. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2012-01-07 08:07:54 +01:00
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. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2012-01-07 08:07:53 +01:00
Richard Cochran	447d4d442c	udp: bring a warning or error if the driver changes our hwtstamp options. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2011-12-18 09:35:41 +01:00
Richard Cochran	b0d547cac4	udp: use the message logging facility instead of stdio. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2011-12-18 08:21:47 +01:00
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. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2011-12-13 05:28:54 +01:00
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. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2011-11-20 18:31:33 +01:00
Richard Cochran	60f3a85463	Add transport over UDP IPv4. Signed-off-by: Richard Cochran <richardcochran@gmail.com>	2011-11-06 08:16:19 +01:00
