I like it.  For a start, the simplification of the NAPI api was long
overdue, and the damage done by separating the napi_struct is really
minimal.  Overall the tg3 driver just looks a little nicer now, and
that's sweet.

Unfortunately my complete ignorance of netpoll prevents me from making
sensible comment there.  This seems to have slipped in tho:

ISTR that noone is using buggy compilers which required per-cpu
initializations now, so this can simply be dropped.

(The new scheduler code doesn't initialize per-cpu, so if this is a
problem it should be noticed).
