From: "Matt Carlson" <mcarlson@broadcom.com> Date: Mon, 3 Nov 2008 02:10:57 -0800 > DASH firmware runs on the APE side of the chip, but it requires a few MAC > to be programmed correctly. > > When WOL is enabled and management firmware is disabled, incoming > packets are evaluated and discarded at the chip's rule processor. > When management firmware is enabled, the hardware must be informed that > there are agents further up the stack that still use the incoming > frames. Normally management firmware will configure the MAC correctly > on its own, but there can be cases where the setting could get clobbered > by the driver. The first hunk of this patch preserves this setting. > > The second hunk of this patch wipes out the driver present signature of > the APE memory space. By doing so, the DASH firmware can assume > driver absent behavior. > > Signed-off-by: Matt Carlson <mcarlson@broadcom.com> > Signed-off-by: Michael Chan <mchan@broadcom.com> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
