  Hi folks,
            I have redhat 8 installed on an recent Asus L3C laptop. Uses
the 8139too module.
Ethernet seems to work, but
i/s very slow /(about 500k/sec) sending data *from* the laptop. (The
other way is ok).
Massive collisions seem to occur (see below)
Anybody have any idea?

    Thanks in advance,
                James.
