I will probably form all required headers in hardware, since the required payload is constant size - always 188 bytes.

Edit, probably the idea is not quite OK. Two reasons why:

2) I am not sure, but if the implementation is fully hardware, what about ARP, ICMP and other common things? Will TSE do that?
