    hi
    In ieee 802.3 CSMA/CD, is it possible that i could check a register value
    set by hardware card or by some other way i could detect in the driver, as
    soon as the card senses that there is a packet on the wire ( i.e. even
    before the reception of the whole packet).

    Anybody's help would be highly appreciated.
    thanks
    vaibhave
