That's clear.

:)
I think my problem is not that hard. This bug only occurs when you are
using CURRENT (or 5.0 RELEASE) from (I think) the point where BPF changed.

Yes. That's very dramatic. :)

Thanks.
BTW, it still doesn't work.
I do:
kldload ng_fec
ifconfig fxp0 up; ifconfig fxp1 up
ngctl ... (exactly what's in sample_script)
ifconfig fec0 1.2.3.4 netmask 255.255.255.252 up
route add default 1.2.3.3
1.2.3.3 does not answer for ICMP pings.
The switch says:
Port-channel13 is down, line protocol is down
Hardware is EtherChannel, address is 0000.0000.0000 (bia 0000.0000.0000)
MTU 1526 bytes, BW 10000 Kbit, DLY 1000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Auto-duplex, Auto-speed
input flow-control is off, output flow-control is off
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output never, output hang never
I got two kernel messages regarding that the interfaces are up in the
etherchannel. If I pull out one of the cables and reconnect it I get the
down/up normally.
It seems that I can't crash now with tcpdump.
I see the incoming packets on fxp[0-1], I see the outgoing ones on fec0,
but there is no connection between the two groups.
> Like I said, it depends on time and availability of resources.
Sadfully, I can't provide you more time, but can provide remote access to
resources.
