    Subjectns83820 - Strange behavior w/Dlink DGE-500T
    From
    With a Dlink DGE-550T and the 2.4.22 ns83820 driver, I'm seeing some
    peculiar behavior. After installing the kernel module and bringing up
    the interface, I see a lot of:

    Oct 16 18:44:39 slate kernel: eth0: link now 1000 mbps, full duplex and up.
    Oct 16 18:44:42 slate kernel: eth0: link now down.
    Oct 16 18:44:45 slate kernel: eth0: link now 1000 mbps, full duplex and up.
    Oct 16 18:44:47 slate kernel: eth0: link now down.
    Oct 16 18:44:50 slate kernel: eth0: link now 1000 mbps, full duplex and up.
    Oct 16 18:44:53 slate kernel: eth0: link now down.
    Oct 16 18:44:55 slate kernel: eth0: link now 1000 mbps, full duplex and up.
    Oct 16 18:44:58 slate kernel: eth0: link now down.
    Oct 16 18:45:01 slate kernel: eth0: link now 1000 mbps, full duplex and up.

    Adding several seconds of sleep after the insmod and again after bringing
    the interface up makes just one or two of these happen.

    Attempting net traffic without the sleep commands leaves the above
    bouncing happening continuously until traffic attempts stop.

    Once the network is up, the bouncing never happens anymore.

    I've tried two different DGE-550Ts, a different switch, and a
    different cable, but the problem seems consistent.
