Rozycki" Date: Mon, 4 Dec 2006 15:04:55 -0800 Subject: [PATCH] declance: Support the I/O ASIC LANCE w/o TURBOchannel The onboard LANCE of I/O ASIC systems is not a TURBOchannel device, at least from the software point of view. Therefore it does not rely on any kernel TURBOchannel bus services and can be supported even if support for TURBOchannel has not been enabled in the configuration. Tested with the onboard LANCE of a DECstation 5000/133. Signed-off-by: Maciej W.
