Hi Ramesh, I cannot see the 10ms comparison you have mentioned in MnpCheckPacketTimeout(). Quick code analysis suggests that received packets enqueued in the specific MNP instance queue have timeout value assigned to them. See MnpQueueRcvdPacket() line:
RxDataWrap->TimeoutTick = Instance->ConfigData.ReceivedQueueTimeoutValue; I believe that you can prevent packet timeout timer event from dropping those packets by setting ReceivedQueueTimeoutValue to 0 upon calling MnpInstance->Configure() function.

This interval is OK when we have the On board / Add on network controllers. In the cases of Network devices exposed via Inband (Virtual USB exposing network interfaces) when there is a packet read given to USB interfaces and it processed in lower level which could not provide the data within the 10 ms interval and it failed with timeout and communication failed when we perform the HTTP request. Do we have any specific reason to have this as 10 ms? Do we have any max limit for this interval value?
