Here's my declaration struct rcf { unsigned broadcast : 3; /* broad- or uni-cast, warning! */ unsigned bridges : 5; /* hop count, we use 8 as max */ unsigned direction : 1; /* which way to read the route */ unsigned length : 3; /* mtu, we use ether mtu for sanity */ unsigned reserved : 5; /* reserved */ } My guess is that someone has stuck a printf in the lan_output() routine, or in the lan_output_llc() routine (somewhere between lines 1000 and 1200), although there are a few other points in the driver where the rcf is being manipulated, these seem the likely spots for your mystery printf.
