Merge branch 'net-convert-tasklets-to-use-new-tasklet_setup-api' 

Allen Pais says:

====================
net: convert tasklets to use new tasklet_setup API

Commit 12cc923f ("tasklet: Introduce new initialization API")'
introduced a new tasklet initialization API. This series converts
all the net/* drivers to use the new tasklet_setup() API

The following series is based on net-next (9faebeb2)

v3:
 introduce qdisc_from_priv, suggested by Eric Dumazet.
v2:
  get rid of QDISC_ALIGN()
v1:
  fix kerneldoc
====================
