I'm being curious, but I failed to found some changelog or discussion about knet
development, history and such decision. Any pointers?

Thanks!

Hi,

we discussed it between team members on IRC.

The implementation in knet has some bugs that noone had the time to 
address and we have been hitting a lot of instabilities while running CI 
tests across different distros/kernel combinations, due to different 
implementations of SCTP at kernel level itself, that makes it rather 
challenging to have a functional userland.

Based on the bugs reports that we receive, noone is using SCTP for what 
we know (I think one was reported over the last 4 or 5 years? and I know 
the code has bugs...)

1.x will continue to ship the code, it?s one --enable-* away.

Since knet allows runtime reconfiguration of links, switching to UDP 
will be a 0 downtime change.

Cheers
Fabio
