From cd0526dce8703bce12763c5c9bfc51f6d27f16c2 Mon Sep 17 00:00:00 2001 From: Rodolfo Alonso Hernandez Date: Fri, 9 Oct 2020 13:26:33 +0000 Subject: [PATCH] "scope" conversion only just before pyroute2 method call In "IpAddrCommand.list" method, the "scope" parameter is a string ("link", "site", "global" or "host"). This method will retrieve all devices with an IP address calling "ip_lib.get_devices_with_ip". Since [1], "ip_lib.get_devices_with_ip" makes the conversion of "scope" string parameter to pyroute2 format (see "pyroute2.netlink.rtnl.rtscopes"). The list command should skip then the previous conversion.
