[LU-10214] Example `lnet_routes.conf` syntax for gateway range is not supported

Duplicate — Wed, 1 Aug 2018 21:18:57 +0000

The default lnet_routes.conf file provided by the lustre-client-2.10.1-1.el7.x86_64 RPM contains an example using an IP range syntax to specify multiple gateways, that doesn't seem to be supported by lnetctl:

tcp7: { gateway: 10.3.3.[6-12]@tcp, priority: 20, hop: 8 }

When feeding that example file to lustre_routes_config, the following error is generated:

# lustre_routes_config  /etc/lnet_routes.conf
Can't parse gateway NID "10.3.3.[6-12]@tcp"

The easy fix would be to remove the example from the configuration file, but a much better one would be to make {lnetctl}} accept IP ranges.

The previous way of handling lnet configuration via kernel module options supported the syntax, so it appears like lnetctl not supporting it is a regression.
