No, this is not the 1990's, please never add new module parameters to
drivers. If not for the basic problem of they do not work on a
per-device basis, but on a per-driver basis, which is what you almost
never want.

But why would you want to change this value, why can't the driver "just
work" and not need manual intervention?
