Device discovery limit #194

Hi, I have run into an issue where not all avdecc devices on a network can be discovered by the controller. If more than 34 devices are online and the controller starts up you only ever see 34 of them. if you however increase the number of online devices one by one after the controller is running it seems to be fine. It looks to be the same on different switch and device layouts as well. Have not done in depth debugging of the controller or network traffic on this, but does anybody have an idea to what this might be related? Thanks!

Something similar to this has been observed, but only for more than 256 devices. 34 devices should not have any issues - at least not from the avdecc-lib side. You should make sure that the end stations are correctly returning UNIMPLEMENTED for unimplemented commands and not just timing out because timing out will cause a retry/resend of the command.
