Release 22.09

[svpcom]

This release include major protocol changes and incompatible with previous releases.

Main changes:

1. Added WFB-ng standard draft. We announce standard draft for long-range data transmission via raw wifi radio.
2. WFB-ng now supports multiple links out of box. You can use one GS for multiple drones control (channel bandwidth will be shared between all of them)
3. Added missing libsodium init. You will be warned if not enough entropy is available.
4. WFB-ng wifi cards now will be automatically set to unmanaged state in NetworkManager during service startup. No need to add them manually to NetworkManager.conf anymore.
5. LDPC now enabled by default due to most of the setups use rtl8812au cards. If you use Ralink or Atheros cards you need to disable it in config file.
6. Added project logo.

thank you very much

[akhaldi]

could you please help us to know how have you managed to debug this issue from my rpi boot log
to speed up the process for future kernel updates
thanks

[svpcom]

From kernel log I've got a stack trace that ends with: recvframe_chk_defrag -> rtw_list_insert_tail -> NULL pointer dereference
Then I've compared diff of v5.2.20 with v5.6.4.2 and found that there is a patch for recvframe_chk_defrag that has fix for uninitialized pointer in that function. We unable to use v5.6.4.2 because it has broken TX power (unable to maximize TX power compared to v5.2.20)
