SoftROCE is a bit of a hot mess in upstream right now. It's
getting a lot of attention, but it's still pretty shaky.
If you're testing, I'd STRONGLY recommend SoftiWARP.

Hello Steve,
Please refer to the page below to configure soft-ROCE:
https://support.mellanox.com/s/article/howto-configure-soft-roce
These kernel configs have to be turned on:
CONFIG_CIFS_SMB_DIRECT
CONFIG_SMB_SERVER
CONFIG_SMB_SERVER_SMBDIRECT
And you can mount cifs with SMB-direct:
mount -t cifs -o rdma,... //<IP address of ethernet interface coupled
with soft-ROCE>/<share> ...

Hi Steve,
Namjae and Hyeoncheol,
Have you had any luck setting up virtual RDMA devices for testing ksmbd
RDMA?
You seem to be asking about soft-ROCE(or soft-iWARP). Hyunchul had
been testing RDMA
of ksmbd with it before.
Hyunchul, please explain how to set-up it.
Thanks!
(similar to "/usr/sbin/rdma link add siw0 type siw netdev etho" then
mount with "rdma" mount option)
