...kup bonding for a switch IOS upgrade in a production environment. Basically I have the VM running on a bridged network which is also tied into GNS3 simulating a small-scale version of the production environment. I have tried bringing down the vnetX interface and the actual virtual network itself (virbrX) with no luck. Has anyone had to do this before/maybe knows some tips? If more info is required about my setup, I can give it. Thanks! Tait

Possibly for post 1.40. Rich.

Let's actually compile and test the patch this time, rather than trusting the RHEL 7.6 patch to apply directly to head ... Rich.

v3: - Various changes to dhclient/dhcpcd as discussed on the mailing list.

v2: - Make virbr0 configurable. - Fix the tests.
