It looks like wl1251 driver supports standard way to set=20
regulatory settings. There is application which reads CAL data,=20
cellular network info, ... and sent it to kernel (via Nokia=20
specific netlink interface patch). And binary data which are sent=20
are in same format as file wl1251-nvs.bin. And some bits which=20
deterministically send to kernl depends on fcc.
