IC Plus Corp. owns the Sundance Tech ehternet chipset business since 2004. The IP100A chipset has appeared in several inexpensive network cards by D-Link and Encore (I bought one of each last week, lucky me) and as the chipset of integrated network interfaces of latest model mainboards manufactured by ABIT, ASUS and Nvidia.

The chipset manufacturer supplies its own version of the ste driver (<>), but it is based on 4.x code. I would like to see the fix (which is trivial as seen in the patch below) integrated in FreeBSD. Please notice that, as seen in the vendor's website mentioned above, the ST201 chipset is now known as the IC Plus Corp. IP100 chipset.

Install PCI ehternet card or use mainboard with integrated ehternet chipset (e.g, ABIT KU8/KV8//AX8/NF7-S2, ASUS P4B266/P5GD1-VM, etc.). It isn't recognized by any network driver in the distributed GENERIC nor SMP kernels.
