A colleague pointed me to the stack (HEAD) no longer emitting DSACK options a few days ago...

I was under the impression, that older versions of FreeBSD would send out DSACKs for spurious duplicate packets.

But when I try this script against HEAD, regular cumulative ACKs without DSACK blocks are showing up.

Currently bandwidth starved - but was that a conscious decision? Or was me observing DSACKs never a thing?

Thanks a lot,
