[elrepo] mac802154_hwsim kmod request

[Tamas Csirszka]

Hi Phil,

That's amazing!!!
It's fantastic news, as the ml kernel while had the module in now and we
could use it on a standalone machine(and enabled our user to continue his
dev work with it), but at the same time we were struggling to integrate it
with the DCOS/Mesosphere app, which had other compatibility issues with
that very new 5.8 kernel.

Let me test this now and will report the results back to you shortly.

Many thanks,
Tamas
