This is very vague. Consider:
For symmetric Toeplitz, four inputs are prepared as follows:
- src_addr | dst_addr
- src_addr ^ dst_addr
- src_port | dst_port
- src_port ^ dst_port
and then passed to the regular Toeplitz function.
It is important to be as specific as possible
so that readers don't have to guess.
Thank you.
