[riot-devel] gnrc_networking packets incoming

Hi Alessandro,

gnrc_networking registers the "pkt_dump" module as UDP server.

https://github.com/RIOT-OS/RIOT/blob/master/examples/gnrc_networking/udp.c#L108

You can find the implementation here:

https://github.com/RIOT-OS/RIOT/blob/master/sys/net/gnrc/pktdump/gnrc_pktdump.c 
.

Just write your own minimal server and register its pid instead of the 
pkt_dump module. You should additionally remove USEMODULE += 
gnrc_pktdump from the Makefile.

Best
Peter
