Unfortunately with the snoop bound to ETH_P_ALL nothing seems
to go out of the real interface while with the snoop bound to
ETH_P_IP it works. There is some wierd interaction going on
here somewhere (I've sent Alexey some traces that I find dubious).
It doesn't seem unreasonable to be able to snoop a specific
protocol in both directions rather than snooping everything
and having to filter it in the application. Is there some
standard we are following here?
Something else is that diald really wants to know whether
a packet is being received or transmitted on the interface,
regardless of whether it orginated locally or is being forwarded
for someone else. Taken with the above it sounds as though we
could have some socket options on packet sockets which would
allow processing of received/transmitted packets to be enabled
and disabled. These could default to the current behaviour
unless changed with setsockopt. Is that at all reasonable?
