Lars can apparently not reproduce it any more. I'll consider this
issue fixed until it returns. Thanks for checking.

Not too bad: it trashes data fast enough :o)
Can you do the same test but send the traffic from the host which
embeds the r8169 ?
The sis190 should not be responsive during the flow. I expect that it
will happily return to a normal state once the traffic stops.
If it behaves correctly, I'll send a first version for inclusion.

One should expect some messages to appear in the log after you forced
the link at 10Mb/s. Do you notice anything in dmesg ?
I would be interested to know if the attached patch makes a difference
(the patch applies on top of the current driver).
Can you issue a simple 'ethtool -s eth0 autoneg off' and report what
happens ?

Sorry, it was just a notice for Lars

Do not update StationControl after the link was forced.
