Configuration query

The program must print a list of zero or more key phrases, one per line, on standard output.^7.1

The following key phrases are recognized by tcc:

all

external program handles the complete traffic control subsystem configuration, including device setup, queuing, etc. This mode can also be enabled by specifying the external program with -x all:external_target

debug_target

target has only debugging functions and does not generate any elements

fifos

tcc automatically adds a FIFO queuing discipline to each class that could have a child queuing discipline, if no queuing discipline is explicitly configured there

nocombine

do not combine individual if clauses into a single classifier. This can tremendously accelerate the processing done by tcc, by offloading work to the external program. The implications of this are discussed in more detail in section .

nocontinue

this key phrase is only recognized for backward compatibility and has no effect

nounspec

the external program does not handle the ``unspec'' classification result in queuing disciplines, so tcc needs to generate rules to implement default actions of queuing disciplines
