           Summary: sundance driver lacks support for IP 100Achipsets (with
                    patch)
    Kernel Version: 2.6.17-rc6
            Status: NEW
          Severity: normal
             Owner: jgarzik at pobox.com

A few days ago I bought a cheap ehternet adapter to replace my old one which
died suddenly. It happened to use an IC Plus Corp. IP100A chipset that is not
recognized by neither the kernel of my distro of choice nor the latest vainilla
kernel. I found a heavily patched driver at the vendor's site,
http://www.icplus.com.tw/pp-IP100A.html that I am not qualified to evaluate.
After some examination and experimentation, I decided to patch the vainilla
kernel sources with the minimal modifications required to have a working network
interface. The changes are very small indeed and done against a copy of
sundance.c obtained directly from the git repo at kernel.org as of today. I'm
using the patched driver now without apparent trouble.

Here is the listing (please let me know if this should go to lkml instead):
