Christoph,

The api was put in to support lpfc sizing async receive queues.  Idea 
was not to have the lldd snoop the LS payloads, thus the transport will 
call the lldd when the LS created or deleted a queue.

It turned out better for lpfc to dynamically grow its pools based on 
demand rather than queue sizing, so the api was moved away from. I 
continued to post it, thinking it may be useful for another lldd 
implementation, one that may actually create hw queues to map 1:1 to the 
queues.

Given there are no current consumers, I've removed it from the next posting.
