Kernel param for SCTP socket buffer size missing in recent Docker Desktop's linuxkit

Docker Desktop

The net.sctp.sctp_rmem and net.sctp.sctp_wmem kernel parameters are missing in recent verions of Docker Desktops linuxkit. They are for tweaking SCTP socket read/write buffer sizes.

These params are crucial if you need large SCTP message sizes, anybody knows what caused this and how do I bring them back?

I’m using Docker Desktop 4.36.0 for Macos Sequoia on Apple Silicon chip.

I don’t know, but it is not available in Docker Desktop v4.35.1 either. Which was the last version in which you could use these parameters?

Not really sure, I will try with older versions but first I have to backup my containers and it will take some time.
Meanwhile I noticed that the params:

net.core.rmem_default
net.core.rmem_max
net.core.wmem_default
net.core.wmem_max

are also missing. And they are as much important as the others.
