With some guidance from the DVSwitch Team I've added a new "LOOSE" option in hblink.cfg for clients.
Setting "LOOSE: True" will relax some of the validation performed on packets received from a master.
This enables HBlink and its associated programs to connect to networks that are slightly out of spec, such XLXD and DMR+
If you wish to use this new feature you will need to "pull" the latest update from Github, and update your .cfg file.
Thanks to the DVSwitch team for accepting the change and their continued efforts.
