Implement processing of the ML element in the association
request, including processing of the per station profile.
After handling the basic parsing of the element, extracting
the information about the requested links, handle the link
specific processing for each link:
- Find the interface with the corresponding link ID.
- Process the station profile in the interface.
- Prepare the per station profile to be included in the
ML element in the association response.
