Read-only values should be marked with const to help the compiler optimize code. But this would requrire a bigger rewirte of all the code, hence the original code did not use const at all. This should be done in the future to ensure good code quality and performance. Signed-off-by: Daniel Danzberger <daniel@dd-wrt.com>
