>Description:
      aue driver will only talk to other systems on the network if the
      interface is set to promisc with ifconfig.  When set to promisc
      while network communications is possible it is slow.  Ping times
      to a any system on the same HUB are in the order of 25 ms
      while ping times ping times between other hosts are in the order of 
      5 ms.

      This was tested with 2 different known working aue devices, both of
      which worked correctly on Linux systems with 2.4 and 2.6 kernels.
      Things also worked fine with a 2.4 linux kernel installed on the 
      same hardware  that has the 7.2-RELEASE on it.

>How-To-Repeat:
      Install an aue based usb device as your network interface.
>Fix:

     No idea!
