[App_rpt-users] RTCM Inbound (Eth Rx) packet out of bounds

I would not put my link in half duplex as it will put a lot more latency
then in full duplex, if auto negotiate is a problem you can still keep the
link in higher speed and full duplex, it is just if the hardware facing the
rtcm that is not fully compatible at the hardware level as the speed
negotiation is a hardware thing, not a tcp/ip protocol thing.
One other thing, if you ever have one device on the network that start
broadcasting a lot if it has a 100 Mbps connection to your switch/router it
will over saturate the 10 Mbps link and make it loose a lot of packet. Even
if it's just using 20 Mbps for its broadcast it will be twice the bandwidth
the rtcm can handle. Be careful with such setup. I had a place where a 10
Mbps alarm system it would signal a trouble as soon someone would listen to
a ip radio station cause the router/proxy was converting multicast packet
as broadcast packet to the local network. The poling packet from the
central station was lost in noise...
