     I have setup ng_fec on a machine with a quad ethernet NIC :

    de0: <Digital 21140A Fast Ethernet> port 0xd000-0xd07f mem
    0xe3000000-0xe300007f irq 9 at device 4.0
    on pci2
    de0: Cogent EM440TX 21140A [10-100Mb/s] pass 2.2
    de0: address 00:00:d1:1c:c3:a1
    de1: <Digital 21140A Fast Ethernet> port 0xd400-0xd47f mem
    0xe3001000-0xe300107f irq 5 at device 5.0
    on pci2
    de1: Cogent EM440TX 21140A [10-100Mb/s] pass 2.2
    de1: address 00:00:d1:1c:c3:a2
    de2: <Digital 21140A Fast Ethernet> port 0xd800-0xd87f mem
    0xe3002000-0xe300207f irq 10 at device 6.0
     on pci2
    de2: Cogent EM440TX 21140A [10-100Mb/s] pass 2.2
    de2: address 00:00:d1:1c:c3:a3
    de3: <Digital 21140A Fast Ethernet> port 0xdc00-0xdc7f mem
    0xe3003000-0xe300307f irq 11 at device 7.0
     on pci2
    de3: Cogent EM440TX 21140A [10-100Mb/s] pass 2.2
    de3: address 00:00:d1:1c:c3:a4

     Commands are :

    #!/bin/sh
    ngctl mkpeer fec dummy fec
    ngctl msg fec0: add_iface "de0"
    ngctl msg fec0: add_iface "de1"
    ngctl msg fec0: add_iface "de2"
    ngctl msg fec0: add_iface "de3"
    ngctl msg fec0: set_mode_inet
    ifconfig de0 promisc
    ifconfig de1 promisc
    ifconfig de2 promisc
    ifconfig de3 promisc
    ifconfig fec0 promisc

     So, I dhclient fec0 and I have :
    > ifconfig fec0
    fec0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
            inet6 fe80::200:d1ff:fe1c:c3a1%fec0 prefixlen 64 scopeid 0xd
            inet 10.200.1.205 netmask 0xffffff00 broadcast 10.200.1.255
            ether 00:00:d1:1c:c3:a1
            media: Ethernet none
            status: active

     I have all 4 ports connected to the catalyst. From what I have read on
    fast etherchannel in the cisco docs, it is supposed to detect the
    etherchannel,
    e.g. no commands at the switch. Lights blink on and off, change color
    (orange -> green) and it seems to work ... but only on one interface in the
    bundle. No faster than 80Mb. I have a 1000Mb intel card in the 2nd
    test machine that does run much faster than 100.
     So, is there something I have done wrong, or what? What should I expect
    to get from 4 x 100 Mb ports?
