[LU-12626] Attempt to create existing net returns EINVAL

Related — Mon, 9 Dec 2019 20:08:34 +0000

When "lnetctl net add" is called for an interface/net pair that already exists, the error code returned is EINVAL. It should be EEXIST, so the user knows that the net is already configured.

[olaf@diane lustre]$ sudo lnet/utils/lnetctl net add --net tcp1 --if enp0s3
[olaf@diane lustre]$ sudo lnet/utils/lnetctl net add --net tcp1 --if enp0s3
add:
    - net:
          errno: -22
          descr: "cannot add network: Invalid argument"
