Intel AC 8260 firmware does not load
Adapter is recognized during the system boot, but doesn't show in the `ifconfig` output.
I have tried both compiling `iwm` in the kernel and adding it as a module in the loader.conf.
I'm running DragonFly 5.0.2-RELEASE on the ThinkPad X1 Carbon Gen4.
Dmesg shows the following errors:
iwm0: <Inter(R) Dual Band Wireless AC 8260> mem 0xe1000000-0xe1001fff at device 0.0 on pci4
iwm0: fw chunk addr 0x404000 len 712 failed to load
iwm0: iwm_pcie_load_section: Could not load the  uCode section
imw0: iwm_start_fw: failed 60
iwm0: Failed to start INIT ucode: 60
Same thing on my Thinkpad T580, un dev version from Apr 18. 2018. Please see screenshots.
The card is reported as 8265 / 8275.
1. In the iwm manual it says: "This driver requires the firmware built with the iwmfw module to work." I'm total newbie for Dfly - do I need to do something special here? Only thing I did was adding if_iwm_fw="YES" into boot/loader.conf, otherwise there was no driver attached to the device.
2. I'm thinking - maybe the card is actually 8275 and the driver supports only 8265 at the moment?
