Re: [PATCH-next 11/25] lnst.Devices.Device: add ips_filter method
On Mon, 2018-05-21 at 10:42 +0200, olichtne(a)redhat.com wrote:
From: Ondrej Lichtner <olichtne(a)redhat.com>
The method retuns a list of ip addresses that match the provided
selectors. The selectors are key=value pairs where 'key' is some
attribute of the ipaddress object, if an ipaddress object matches all
the selectors it is added to the return list of the method.
