Remove the if condition which is always false. The last update on
variable max_rf_path is value 1. It's value is not changing after that.
So if condition check for value 2 will be always false only.

If the condition is always false the whole block can be wiped out,
why did you keep it? Did you change the logic here?

Thanks for review Fabio.
It is changing the logic . I should be careful for this. whole block of
if statement should also be removed.
Please ignore this patch.

Saurav

Yep. And please go through the function and clean up all the references
to max_rf_path. Change the "max_rf_path = 0" to 1 and delete the other
assignment. Delete the comments about "max_rf_path == 2".

Yes, Is it good if I send 2 patches one to remove "if condition which is always
false" and another one to "clean-up all the references to max_rf_path" on a single
patch series.
