[fedora-arm] Install Fedora server 30 on Raspberry 3

I installed Fedora 30 Server on Raspberry 3.
after I plug the power cord. Fedora starts to boot after sometimes I see this message

lan78xx_eth waiting for PHY auto negotiation to complete

and boot process stop.
I must press Ctrl+C on a keyboard and after that Fedora server continues it booting.
when fedora boot reaches to something like grub, I must press Enter again to boot process continue again.
I want to connect raspberry to hidden network and I need MAC address of Wlan0, when I type

ifconfig

I see mac address of Wlan0, and I add my mac to my router for mac filter, but after sometimes when I run

ifconfig

again I see different mac address for Wlan0 and I think every time mac address is changed automaticaly.
It is how odd why mac address of wlan0 change!!!
and I want to connect to a hidden network with mac filter on the router.
how I can solve this problem?
I want to use this fedora server as a server for my network. I want fedora boot without keyboard and monitor and fedora boot without problem.
I want to control my system over wifi network by SSH.
what I must do?
I think Fedora server on Raspberry 3 has some bugs
