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.
