I'm studying how Netgraph system works and trying to write my own
netgraph node similar to ng_bridge.
It catches packets from lower ng_ether hooks and transmits it to other
interfaces using mac address hashtable.
Packet processing in my node implemented similar to ng_bridge_rcvdata()
I don't do anything with packet. I don't modifying packet header, I only
send it to another interface.
My interfaces are working in promiscuous mode with autosrc=0.
But sometimes (after one or two hours working in network) I have an
error with message:
"rl1: discard frame w/o packet header"
After it, my system halts.
Is anybody knows, where the problem can be? When does this message appears?
(system is FreeBSD 7.1-STABLE)
