WiFi adatper not working, failed to load init firmware

[dsjonny]

Using hrev56261 x86_64 nightly image the wifi adapter found, but with no MAC address.

In the log there is failed to load firmware message: KERN: idualwifi7260: failed to load init firmware

I tried it with Lenovo T450 with 2 different wifi adatpters (7265 and 8260). Both adapter are found and visible in the Network.

I also checked the Bluetooth, and for that I see MAC address, and found Bluetooth devices, but unable to connect those.

syslog attached.
