hi
in wikipedia i found

In some networks, such as IEEE 802 local area networks, the Data Link Layer is described in more detail with Media Access Control (MAC) and Logical Link Control (LLC) sublayers; this means that the IEEE 802.2 LLC protocol can be used with all of the IEEE 802 MAC layers, such as Ethernet, token ring, IEEE 802.11, etc., as well as with some non-802 MAC layers such as FDDI.

Again the type of OS is non specific, but can use linux as example

So the question is, practically does the LLC know what type of Mac (802.3 or 802.11) it is using or does it not?
Is there a module in the LLC which detects the type of MAC or medium it is interfacing with, or is the interface between the 2 well defined so that it does not know.

Logically since they are sublayers, they should have a well defined interface so that you can change the MAC (and medium) at any time, and make use of multihoming features.
But since the LLC takes care of error correction, flow control and is the logical brain of the physical link, should it not know what type of MAC it is interfacing with?

thanks in advance
