Please see this message from yesterday:

  http://lists.gnu.org/archive/html/discuss-gnuradio/2009-03/msg00466.html

Try the new firmware without forcing anything with ethtool.  (Leave
autonegotiation enabled.)  It should come up with a sensible answer.


On my system I get:

    address@hidden trunk]$ ethtool -a eth1
    Pause parameters for eth1:
    Autonegotiate:  on
    RX:             on
    TX:             off

Which is what I expect.
