Failure to negotiate with 100Mb hub
Sat Aug 7 20:02:09 1999
I've an Intel eepro 100B (chip 82557, board rev 8) under Linux 2.0.36
(RedHat 5.2) that refuses to finish negotiations with a Linksys fast
ethernet 5-port hub (model FEHUB05W). The eepro100 driver is v1.08 and
is being used as a module. The eepro_diag and mii_diag programs seem
to indicate that it fails during negotiation (negotiated status is
incomplete and the "link partner capablility" byte is zero). Visually
it looks like the boards sends a packet out every second or so,
presumably to re-negotiate.
This same board with the same hub negotiates -- and works -- correctly
I tried using fixed attributes to force the board into the proper
state but this seemed to confuse the it even more. The board sends
a constant stream of data to the hub and the diagnostics, while
showing the correct forced state, still shows that negotiation failed
to complete. While in this state I can turn network services off and
rmmod the eepro100 driver and it makes no difference to the data stream
being sent by the card. In fact I can shutdown the system and the
datastream continues until reset or power off.
I've given up on the problem for now and went and bought a 10/100
switch instead and the card/driver combination works great with that.
However, I thought that this data point might be useful in correcting
