====================
net: some build fixes and other improvements

A few unrelated improvements here, mostly trying to make random
configs build and W=1 produce a little less warnings under net/
and drivers net/.

First two patches fix set but not used warnings with W=1.

Next patch fixes 64bit division in sch_taprio.c.

Last two patches are getting rid of some (almost) unused asserts
in skbuff.h.
