>
> Replace custom interrupt tracker with generic xarray data structure.
> Remove all code responsible for searching for a new entry with xa_alloc, which always tries to allocate at the lowes possible index. As a result driver is always using a contiguous region of the MSIX vector table.
>
> New tracker keeps ice_irq_entry entries in xarray as opaque for the rest of the driver hiding the entry details from the caller.
