Node Description is writable on the host. You can write to:
/sys/class/infiniband/<ib-driver><number>/node_desc
e.g. (for Mellanox HCAs)
/sys/class/infiniband/mlx4_0/node_desc
/sys/class/infiniband/mthca0/node_desc

There's a diag script which does this:
set_nodedesc.sh
At older diag versions, it had a slightly different name.
