ok, thanks for the explanation.
Steve mentioned an update to the man page is needed as well. Please do
that in the respin.
Thanks,

Sorry for being slow in response, I was on vacation.

This print is intended to warn about missing "new name" and it is not
checked by rd_exec_require_dev()
To emphasize it:
diff --git a/rdma/dev.c b/rdma/dev.c
index 760b7fb3..468ae686 100644
--- a/rdma/dev.c
+++ b/rdma/dev.c
@@ -246,6 +246,7 @@ static int dev_set_name(struct rd *rd)
uint32_t seq;
if (rd_no_arg(rd)) {
+ pr_err("hello world\n");
pr_err("Please provide device new name.\n");
return -EINVAL;
}
Produces the following output:
[leonro@server iproute2]$ ./rdma/rdma dev set mlx5_0 name
hello world
Please provide device new name.
So how will we progress from here? Should I respin?
Thanks

This is redundant with rd_exec_require_dev which is the required path to
get to this point.
