Author: marius Date: Sun Sep 20 12:08:29 2009 New Revision: 197343 URL: http://svn.freebsd.org/changeset/base/197343 Log: MFC: 194246, 194904, 194973 Add cas(4), a driver for Sun Cassini/Cassini+ and National Semiconductor DP83065 Saturn Gigabit Ethernet controllers. These are the successors of the Sun GEM controllers and still have a similar but extended transmit logic. As such this driver is based on gem(4). Thanks to marcel@ for providing a Sun Quad GigaSwift Ethernet UTP (QGE) card which was vital for getting this driver to work on architectures not using Open Firmware.
