I've figured out a way to retrieve a frequency value via netlink:
By passing the lora0 ifindex in as attribute, nllora can look up the
net_device by index, and then via struct lora_dev_priv call into hooks
that the device drivers can optionally implement. :)

Tested with HIMO-01M module.
The command might need an additional channel attribute for SX130x.

The corresponding nltest program (using libnl-genl) is here:

Cheers,
Andreas
