Hi,
I am wondering if it is a bug of ng_pppoe.
The objects that have the structure sess_neg hold a pointer on the last sent
packet.
struct sess_neg {
struct mbuf *m; /* holds cluster with last sent packet */
union packet *pkt; /* points within the above cluster */
(...)
Then when a packet is made, the same mbuf is always reused. However, m_data
might have been changed by another node or a driver (for example, there are
some pieces of code that translate m_data: m_data += n).
It means that the second time a pppoe packet is sent during the negocation, a
part of the ethernet header is missing.
It think that the problem is related to m_copypacket that is used within
ng_ppppoe in order to keep always the same mbuf.
