Just for clarification:
- Patch "net: lorawan: Add LoRaWAN socket module" is for lorawan module
- Patch "net: lorawan: Add LoRaWAN API declaration for LoRa devices"
containes the header file "include/linux/lora/lorawan.h" which will be
included by LoRa device drivers or other kernel modules.
- Patches "net: maclorawan: Add maclorawan module declaration", "net:
maclorawan: Implement the crypto of maclorawan module" and "net:
maclorawan: Implement maclorawan class module" are for maclorawan
module.

Question 1:
Should I marge "net: maclorawan: Add maclorawan module declaration",
"net: maclorawan: Implement the crypto of maclorawan module" and "net:
maclorawan: Implement maclorawan class module" into a single patch
named "net: maclorawan: Add maclorawan as the soft-MAC module"?

Then:
For example, after a LoRa device driver includes the header
"linux/lora/lorawan.h", the device driver will call "lrw_alloc_hw()"
and pass with a "struct lrw_operations" type of variable's pointer.
It gets a type of "struct lrw_hw *" pointer.  Then, it will call
"lrw_register_hw()" to register the device.  The device driver
implements the callback functions for the "struct lrw_operations" type
of variable by it self before calls "lrw_alloc_hw()".

Question 2:
Should the patch "net: lorawan: Add LoRaWAN API declaration for LoRa
devices" also be merged into "net: maclorawan: Add maclorawan as the
soft-MAC module" or "net: maclorawan: Implement maclorawan class
module"?  Or, just leave it as a single patch?
