`route_get()` compares input with existing routes, however previously,
the input may did not have information about gateway. So, the
comparison result might be incorrect, and the foregoing set_put() might
return -EEXIST.

explicitly specified in the [Route] section.

Strivtly speaking, this breaks backward compatibility. But setting
too large value into them, then their networking easily breaks.
Note that typically 100 for them is event too large. So, ommiting the
values equal or higher than 1024, and dropping support of k, M, and G
suffixes is OK for normal appropriate use cases.
