    This is OT but couldn't get answear on the sources I found and was
    hoping someone can point me in a better direction or is knowledgeable
    and kind enough to help.

    I have an onboard realtech 8139c ethernet card (sony vaio laptop).
    I used ethtool and nictools-pci to diagnose.
    It seems that the card thinks its capable of
    100baseTx-FD 100baseTx 10baseT-FD 10baseT full/half duplex (rtl8139-diag
    -mm)
    I can set any of these modes using ethtool -s eth0 ... and this shows up
    properly using rtl8139-diag
    Using autoneg on against a 10Mps card on other side works fine.
    Against a 100Mps card autoneg agrees on 100Mps but then won't send
    anything. Looking at the output of rtl8139-diag seems to show that the
    sync comes and goes, probably decides on parameters, sees that it can't
    talk and retries to negotiate.
    When setting manaully to 10Mps autoneg off the card works fine.
    When working at 100Mps, tcpdump reports that the card keeps sending arp
    request, and doesn't see any replies.
    Tried to rewrite the eeprom settings using rtl8139-diag but didn't work.

    any ideas?

    thanx
