Added a new layer CDP_IF inside dp which is an intermediate between the data path functions and the upper layers. All function calls from outside the DP layer to the DP layer goes via the CDP_IF layer Change-Id: I76e671c85d2d02aa0a65a90b356840d3aeede52d CRs-Fixed: 1075597

|
* returns 0 to indicate that it needs to consume one more. In this case, the

|
|
* The function is simple and doesn't dynamically take decisions on A-MSDU
|
|
* formation. It can be extended to pack more fragments into an A-MSDU if
|
|
* required, but in this case there can be greater losses due to the
|
|
* environment. The objective of the function is only to simulate regular
