[elrepo] mac802154_hwsim kmod request

Hi Alan,

Different time zone here, hence my late response, but yes, that's quite
embarrassing....
You are absolutely right, I only installed the core package, haven't
noticed that the modules are in a separate package in el8 (not like el7
where everything is in the kernel package)!

After installing the modules rpm, everything is working as expected:

[root at kernel8 ~]# uname -a

Module lodes fine and wpan interfaces are up!

So this means with your updates/addition to kernel config, this driver is
now available on both el7 and el8 using the ml kernel!!
Thank you very much.

Cheers,
Tamas
