I suggest a subsystem match here, or generally some
SUBSYSTEM!="net", GOTO="end_of_file"
around almost all rule files that should not match on network interfaces, as 
users can rename them to almost all crazy names.

@Kay: Perhaps it could simplify some rulesets to have a special jump target or 
option to skip entiere rules files.
