Notes:
    v2: designate the patch to wpan-next and use a subject prefix naming the
    component, as maintainer-netdev.rst asks; v1 went out with a bare
    [PATCH] and a "net:" prefix. Rebased onto wpan-next, diff unchanged.
    
    v1: https://lore.kernel.org/all/20260907064346.3288-1-hemanth.selam@gmail.com/
