[LoRaWAN]

1. ​​In GWT mode, DL MAC commands in Foptions field without payload were interpreted incorrectly so the tester did not send a response to it. It is fixed in this version.

[Pre-Certification]

2. In All Cert 1.4.a.i AES encryption, the maximum payload size could exceed the limit in some cases. It is fixed to be used less than the allowed payload size as per the DR.

3. The RX2 frequency needs to be restored to defaults before starting certification, but the setting of other applications such as link analyzers has been used in the certification. it is fixed to reset RX2 frequency when certification starts.

4. The Frequency offset of AS923 should have been applied to RX2 frequency in LinkADRReq. It is fixed to add frequency offset to the LinkADRReq.

5. In All Cert 14, Prioritizing Multiple MAC Commands, DownlinkDwellTime was set to 1 because it was not mentioned in the specification. It changes to 0.
