> It can be needed to have some MSI-X allocated as static and rest as dynamic. For example on PF VSI. We want to always have minimum one MSI-X on it, because of that it is allocated as a static one, rest can be dynamic if it is supported.
>
> Change the ice_get_irq_res() to allow using static entries if they are free even if caller wants dynamic one.
>
> Adjust limit values to the new approach. Min and max in limit means the values that are valid, so decrease max and num_static by one.
>
> Set vsi::irq_dyn_alloc if dynamic allocation is supported.
