How do I set the subnet rate?

Also, for /etc/rdma/partitions.conf, where would I be able to find what the valid options are for mtu= and rate=?

I’m trying to look for it and RedHat published it, but I have no way of checking or confirming that those options are valid for /etc/rdma/partitions.conf and none of the Mellanox documentation says it as well.

(And I also couldn’t find an OpenSM mailing list to join either where I can ask this question to the developers.)

Thank you.
