IWD not working on rpi-B2

[eponymous]

I was interested in switching from wpa supplicant to IWD, as it seemed to have a lot going for it.

On my RPI-B2 (CPU revision a21041) w/ kernel version 4.14.93-2-ARCH (which I believe is the most recent available), running iwm produces numerous notifications that my kernel is too old and not configured with the necessary options (see below).

Will this be resolved when a more recent version of the kernel becomes available, or am I likely to have to compile the kernel myself to get the necessary options?

Thanks
