[Click] How to reference Method Interfaces?

[Beyers Cronje]

Hi Bjorn,

You have two options, you can pass the queue element name to your element's
configuration and obtain a pointer to it. See staticthreadsched.cc for an
example. Or you can find the queue element names via flow-based router
context, see red.cc for an example on this. This file uses both options, see
RED::initialize() for the flow-based code.
