* Note that in the case of IP fragments, the function takes two fragments at a
|
|
* time and creates an A-MSDU. If it has seen the first of such fragments, it
|
|
* returns 0 to indicate that it needs to consume one more. In this case, the
|
|
* caller shouldn't pass the nbuf to lower layers.
|
|
* 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
|
|
* scatter/gather.
