From: James Smart <[email protected]> [ Upstream commit 9e0e8dac985d4bd07d9e62922b9d189d3ca2fccf ]
The lldd may have made calls to delete a remote port or local port and the delete is in progress when the cli then attempts to create a new controller. Currently, this proceeds without error although it can't be very successful. Fix this by validating that both the host port and remote port are present when a new controller is to be created.
