When doing git bisect on el7 kernels, without setting any specific version on compile, the kernel ends up as version "3.10.0+"

# uname -r
3.10.0+

vdsm-4.30.38-1.el7ev.x86_64 fails to start because of this, when trying to decide between using SFQ or FC_CODEL qdisc:

It's the only daemon that fails to start due to the unusual kernel version and it's a bit annoying when testing.

Perhaps specifically check if the kernel has the qdisc compiled is both less strict and more reliable?
