The logic, though, shouldn't directly return, as the buffer may contain a full packet, and therefore the WAIT_SYNC state needs to be processed (resetting state to WAIT_IP, clearing rx_buf_size and re-initializing rx_buf_missing). So, just let the while loop continue so that in the next iteration the WAIT_SYNC state cleanly stops the loop. The WAIT_SYNC processing will be done just after that, only if the end of packet is flagged. Signed-off-by: Aleksander Morgado Signed-off-by: David S.
