Affects 0.3.0 and earlier but only for 1.1 servers.

The problem occurs in LoRaWAN 1.1 where the channel index as a parameter for generating MIC. LoRaWAN 1.0 doesn't do this.

LDL currently works by sending the exact same frame as before for re-transmission, but usually on a different channel to the original. This also affects "dedicated mac command responses" because the MIC is generated before the channel is selected.

This will be fixed in the next release.
