    Subject[BUG 2.5.67 (and probably earlier)] /proc/dev/net doesnt show all net devices
    Date
    Summary: /proc/net/devices doesnt show all devices using cat. With dd all are 
    available.

    I tested a kernels prior to
    http://linus.bkbits.net:8080/linux-2.5/cset@1.797.156.3
    and it doesnt seem to have this problem.

    If I do a
    & cat /proc/net/dev
    Inter-| Receive | Transmit
    face |bytes packets errs drop fifo frame compressed multicast|bytes
    packets errs drop fifo colls carrier compressed
    lo: 784 10 0 0 0 0 0 0 784
    dummy0: 0 0 0 0 0 0 0 0 0
    tunl0: 0 0 0 0 0 0 0 0 0
    gre0: 0 0 0 0 0 0 0 0 0
    sit0: 0 0 0 0 0 0 0 0 0
    eth0: 1078024 19131 0 0 0 0 0 0 5696472
    eth1:536253967 10078459 0 0 0 0 0 0 3372254868
    I get net devices till eth1, but eth2 and hsi0 are available nevertheless.
    but if I do a

    & dd if=/proc/net/dev bs=4096
    Inter-| Receive | Transmit
    face |bytes packets errs drop fifo frame compressed multicast|bytes
    packets errs drop fifo colls carrier compressed

    0+1 records in
    0+1 records out
    All net devices are shown.

    cheers
