• network/network.c: In some cases it can occur that an empty mbuf is put on the descriptor chain. (We found it especially then when transmitting fragmented IP Packets.) Since the actual buffer descriptor pointer will be incremented after every inserted mbuf (txBd = sc->txBdBase + sc->txBdHead;) even if m->m_len of the current mbuf was zero. This leads to the bug.
