| * 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. |
