----------------------------------------
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 [0] uCode section
imw0: iwm_start_fw: failed 60
iwm0: Failed to start INIT ucode: 60
