True. I meant if respun.

Whether such changes are worth it as standalone patch is subjective.
And I get where you're coming from, given that thread.

Well, FWIW you commented on this in your review, so I figured I'd send it.

Not sure such refactoring patches are worth the effort.

2024-09-30 Thread Sean Anderson
Rename ip_len to payload_len since the length in this case refers only
to the payload, and not the entire IP packet like for IPv4. While we're
at it, just use the variable directly when calling
recv_verify_packet_udp/tcp.
