Overall this looks good. It would be nice to have some support in iwctl 
to see these fields. Those properties and getters/updaters can be 
implemented here if possible:

https://git.kernel.org/pub/scm/network/wireless/iwd.git/tree/client/bss.c

We will need to wait for Denis to comment/merge though.

Thanks,
