provide delete_link function

[ghost]

It would be nice to have a delete_link function (analog to the create_link funcrton) which takes the same parameters (node_a, port_a, node_b, port_b).

Internaly it would need to find the link ID used for that connection and then call the delete() method of the link object.

This would be usefull in updating existing topologies (e.g. when using the ansible modules) in order to not only add missing links, but also remove not needed links from topolgies without the need to remove/delete the complete topology.

We might have a go on that soon, for now this shall serve as a feature request :)

Don't have enough cycles to give this a spin for the time being, it is a good idea to have that method implemented.

Feel free to give it a shot? I can later help on moving this functionality to the ansible modules

Hello all,

I had created the project function to delete the links as required, running on my local lab for now

n [7]: print(tabulate(links_summary, headers=["Node A", "Port A", "Node B", "Port B"]))
