Hi,
I’ve built a filter below IP.
I’m intercepting both ppp and ethernet packets.
Which possebilities do i have to deferentiate between incoming/outgoing
packets of each interface ?

On up headed packets, the cell, endpoint, iface parameters
to your rx_up() func tell you who originated the packet.
On down headed packets, npkt->cell, npkt->endpoint, npkt->iface
tell you where it’s going to (which interface is to put it
out).

Sean,
I’m using 2 interfaces on the same computer: en0, ppp0.
I can see that the only diffreance between the above is on the cell (the
rest are always 0).
ethernet: cell=0
ppp: cell =2
Can i be sure that these valuses will remain the same on diffrent systems
(e.g.: x86, ppc, rpx-lite) with the same identical interfaces ?

It depends on the order things are started in. All “en” are
in a particular cell, all “ppp” are in another etc… When
your filter is mounted, you should receive a msg npkt of
type _IO_NET_MSG_DL_ADVERT for every interface below you.
You can learn who is who this way.
