net/ipv4: queue work on power efficient wq
Workqueue used in ipv4 layer have no real dependency of scheduling these on the
cpu which scheduled them.
On a idle system, it is observed that an idle cpu wakes up many times just to
service this work. It would be better if we can schedule it on a cpu which the
scheduler believes to be the most appropriate one.
This patch replaces normal workqueues with power efficient versions. This
doesn't change existing behavior of code unless CONFIG_WQ_POWER_EFFICIENT is
enabled.
