Call for testers : ALi/ULi M5261/M5263 FastEthernet controller Here is dc(4) patch for ALi/ULi M5261/M5263 FastEthernet controller. I've checked hardware differences between ULi M562x and Intel 21143 controller. It seems it could be supported by modifying dc(4). The controller's data sheet is not available to open source developers so I had to read what differences the controller had and made a patch. Because I don't have ALi/ULi M562x controller it's just guess work so it may not work correctly but I need your feedback to improve driver stability. Please follow the following steps to apply the patch. This assumes you're using FreeBSD 8.2-RELEASE. 1. Download dc(4) sources from latest stable/8 branch. http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/dc/if_dc.c?rev=1.201.2.14;content-type=text%2Fplain http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/dc/if_dcreg.h?rev=1.57.2.7;content-type=text%2Fplain http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/dc/dcphy.c?rev=1.35.2.6;content-type=text%2Fplain http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/dc/pnphy.c?rev=1.23.2.6;content-type=text%2Fplain 2. Copy downloaded if_dc.c, if_dcreg.h, dcphy.c to pnphy.c to /usr/src/sys/dev/dc directory. 3. Download and apply patch at the following URL http://people.freebsd.org/~yongari/dc/dc.uli562x.diff 4. Apply the patch to source directory. #cd /usr/src #patch < /path/to/dc.uli562x.diff 5. Rebuild kernel and reboot. 6. Try some experiments for networks. 7. Send me full dmesg and 'ifconfig dc0' output Thanks.
