Patch to reproduce the bug

The assert that rises:
assert failed. cond="m_buffer.GetSize () >= start + length", file=../src/network/model/packet.cc, line=234

It happens in a scenario with two pairs of AP-STA where each AP is sending data to the associated STA.
I attach a patch of wifi-aggregation example to reproduce the issue.

The problem appears after commit 11945:96b721d35158 which fixes bug 2313.
