Adding new queuing disciplines

If the new queuing discipline requires new parameters, the following files need to be changed:

tcc/Parameters

defines name and type of the parameters. Various include files are automatically generated from this file.

tcc/tcng.l

parses the parameter name and returns a suitable token

tcc/tcng.y

declares the token (in a %token line), and processes the parameter in the parameter_expression rule

For the queuing discipline, a file called q_name.c needs to be written, that provides the functions and data structures that define how the queuing discipline is processed.

In addition to writing the q_name.c file, the following files need to be changed:

Makefile

include q_name.c in FILES

tcc/Makefile

include q_name.o in OBJS

tcc/qdisc.h

add a declaration of the descriptor

tcc/tcng.l

parses the queuing discipline name and returns a suitable token

tcc/tcng.y

declares the token (in a %token line), and processes the queuing discipline in the qdisc_name rule

Also, new elements should be exercised by the regression tests. Adding a new test case involves the following files:

tests/name

the file containing the actual tests

Makefile

include tests/name in FILES
