[~jieyu] I took the liberty of adding you as the shepherd here as the review
was addressed to you.

> I tried to use network/port_mapping isolator and faced this issue:

> * on virtualized environment (KVM, virtualbox, AMIs, etc.)
> * on CentOS 7 with teaming driver enabled, it doesn't report the speed.

> cat: /sys/class/net/team0/speed: Invalid argument
> {noformat}
> Here is a pointer to the code blocks that perform those tests:

> In my opinion, to solve most of these use-cases, we could make those tests

> It could result in an inconsistency between the interface speed and the
> bw_limit set, but I guess there are more benefits in making it usable in more
