Thanks for pointing out.
Still learning...

hertz:~/devel/ethernut_sf/nut> find -name \*.c | xargs grep "HANDLE vol"|wc
     17     147    1502
hertz:~/devel/ethernut_sf/nut> find -name \*.c | xargs grep "ile HANDLE" | wc
      6      34     368
It seems that some ethernet driver introduces volatile in context with
HANDLE and all resulting drivers copied that construct. Should we correct?
