>Description:
When using a the Conexant RS7112 ethernet adapter with a 100Mb link
on my Compaq Presario 1700 notebook, the connection is
unreliable. There are frequent timeout errors,
CRC errors, and send errors. On one switch, the link
light for the connected port blinks constantly, though
the connection is idle. Few packets are not dropped.
Using the NIC on a 10Mb/s switch fixes the reliability problem.
Trying to set the link speed to 10-TX or 10-T no longer works
with recent kernels. Previously, setting the media type
allowed for a reliable link.
$ dmesg | grep tlp0
tlp0 at pci0 dev 9 function 0: Conexant RS7112 Ethernet, pass 0.8
tlp0: interrupting at irq 9
tlp0: Ethernet address <omitted>
ukphy0 at tlp0 phy 1: Generic IEEE 802.3u media interface
tlp0: transmit timeout
>How-To-Repeat:
Use a the Conexant RS7112 ethernet adapter with a 100Mb link.
