Subject: tg3 driver / BCM5722 dropping to 10Base-HD

Hello,

i have a dell with a BCM5722 driven by the tg3 driver.

this pc is connected to an unmanaged switch by micronet;
the connection is at 1000MBs.

the system is normally stable;
sometimes the connection get dropped to 10Mbs/HD.

i can get te connection back up to 1000Mbps
with an ethtool -t eth0.

do you have any idea on what is the cause of this ?
is this the wrong adderess?

please cc: me as i am not subscibed to netdev.

thank you in advance,
 marco,
