Can you describe why you choose the way over the NIC and not over
pcap? When you connect your CAN capture code to pcap you can use some
DLT as it is done for USB or SocketCAN etc.
I know it's a mess, that all CAN device manufacturer provide it's own
API for Windows due to the lack of something like SocketCAN.
