Allow isotp implementation per mailbox

[david-res]

Is there any way that I can assign an isotp callback to a mailbox filter? Similar to how I would assign a custom callback per mailbox? Could this capability be developed?

I am making requests to multiple nodes, and while two of them always have the same ID and can retain the same set of callbacks/response code, one of them (the ECU) varies with up to six different response parsing options and would be easier for me to manage if I can isolate the response logic into separate callbacks per node, as at the moment everything is in one isotp callback, and I need to copy the entire logic between each ECU variant which is prone to mistakes and is taking up memory

per mailbox? not in it's current form, the fixed buffer is a collector of all mailboxes. it would require a rewrite of most of the code to do this

Got it. So ideally a smaller user defined iso tp buffer per MB would be ideal for me. It just makes it easier code wise to reconfig the mb callback/buffer rather than having to maintain multiple versions of the isotp rx callback that contain handlers for multiple IDs
