[RFC 0/2] Net softirq deferring to ksoftirqd

[Dmitry Safonov <dima@arista.com>]

Based on events I've saw on out-of-tree drivers, but I believe that
can happen on the mainstream ones.
I managed to get some results in Qemu VMs, but this lacks testing
on a real mainstream hardware.

Also I'm not sure that's completely sane thing to-do, so sending early
to get some reviews.
