Currently, I use an STM32H757I-EVAL Board, on which I have running a CDC ECM driver for USB to Ethernet capabilities. I have noticed that there are a significant amount of IN tokens being sent out of the Eval Board during a transfer of packets (as per TCP protocol), yet I cannot seem to find where in the drivers this correlated with. Is there a specific place in the drivers I should be looking to find the configuration for this? I am mainly trying to find where tokens are sent via the Evaluation Board, but I am not sure where to look anymore.
I had searched for the keywords "IN," "Token," "Send," and "Receive," but had no luck with any of these searches. Any help or guidance would be appreciated.
Thanks!
