This is a known problem - some archives referenced by my index no
longer work on vanilla Sculpt-20.08. Since I do not plan to update the
archives I removed my index file to prevent others from stumpling upon
this issue.

For some devices the driver will ask for a different firmware version
than is available because the the driver supports a range of different
versions. However, not all supported firmware versions are publicly
available (or were not at the time support for a device was added to
the wifi_drv). In this case we supply the firmware version we have at
hand. If you follow the implementation of 'request_firmware_nowait()'
the intention becomes clear.

I have no experience with BLE; the general approach would be to look at
how other OS' implement the stack - which parts are implemented by a
kernel driver and which parts are implemented as user-land component
and go from there.

One example would by our USB LTE modem stack where we ported the kernel
driver from Linux and created a driver component that presents the data
channel as a Uplink session and the management channel as a Terminal
session. The 'mbimcli' port uses the Terminal session via the libc and
VFS to perform the necessary configuration of the modem while the Uplink
is used to transfer the data. So in this case you have two components,
a driver and a configuration component.

Josef
