The type of the devlink parameters msix_vec_per_pf_{min,max} is
specified as u32, so you must use value.vu32 everywhere you work with
them, not vu16.
I will change it.
You also need a pretty good reason to use u16 anywhere at all.
Just because the domain of the value is small doesn't mean the
best type isn't [unsigned] int.
Any arithmetic (particularly on non x86) is likely to increase
the code size above any perceived data saving.
In 2012 Scott Duplichan wrote *Small Integers: Big Penalty* [1]. Of
course you always should measure yourself.
Kind regards,
Paul
