sis900: phy for FoxCon motherboard
661FX7MI-S motherboard which uses the SiS 661FX chipset. The patch adds
an entry to mii_chip_info for the transceiver.
The PHY ids were found using the sis900_c_122.diff patch from
http://brownhat.org/sis900.html but that patch didn't solve the problem,
because the PHY at address 1 was already being chosen.
Without my patch, when bursts of packets arrive from other hosts on a
LAN, the interface dropped one roughly 10% of the time, causing
retransmits. There were fifth second pauses in refresh of large xterms,
and it made Netrek suck. I can provide further test data.
Workaround in lieu of patch is to use mii-tool to advertise
100baseTx-HD, then force renegotiation.
I wasn't able to identify the actual transceiver, so the description
field is a guess.
This patch is similar to Artur Skawina's patch:
http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2
I'm not sure, but I wonder if it means the default behaviour should be
changed, so as to better handle future transceivers.
