Hi,
I would be interested in getting some feedbacks about people who are using
these boards and these drivers too.
If you need a DVB stack that supports IPv4/IPv6/Ethernet/MPLS over assymetric
links, you can be in touched directly with me or 6WIND.

I am wondering why do we need a new PPP node. There are already so many
implementations. If we need a Netgraph PPP support, mpd + ng_ppp seems to be
enough, doesn't it ?

It is not very simple. However Netgraph/ng_socket.c does something similar.
net_add_domain is called from ngs_mod_event().
However, it is not possible to remove this module because the feature to
remove a domain is missing.

Hi,
With FreeBSD, there are many ways to create a recursive local encapsulation

more complex Netgraph topologies...

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 */
unionpacket *pkt; /* points within the above cluster */
According to Google, there is not support of Netgraph with the Sangoma's
boards.
In fact, I am wondering if I could use the Sangoma's boards like the if_sr
and if_ar drivers that have a nice Netgraph hook.
