+What:		/sys/devices/platform/at91_can/net/<iface>/mb0_id
+Date:		January 2011
+KernelVersion:	2.6.38
+Contact:	Marc Kleine-Budde <kernel@pengutronix.de>
+Description:
+		Value representing the can_id of mailbox 0.
+
+		Default: 0x7ff (standard frame)
+
+		Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
+		"AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the
+		contents of mailbox 0 may be send under certain
+		conditions (even if disabled or in rx mode).
+
+		The workaround in the errata suggests not to use the
+		mailbox and load it with an unused identifier.
+
+		In order to use an extended can_id add the
+		CAN_EFF_FLAG (0x80000000U) to the can_id. Example:
+
+		- standard id 0x7ff:
+		echo 0x7ff      > /sys/class/net/can0/mb0_id
+
+		- extended id 0x1fffffff:
+		echo 0x9fffffff > /sys/class/net/can0/mb0_id

-3.5 Overriding Configuration for Special Cases
+3.5 Configuration with Interfaces Support
+-----------------------------------------
+
+        This section applies to distros which use /etc/network/interfaces file
+to describe network interface configuration, most notably Debian and it's
+derivatives.
+
+	The ifup and ifdown commands on Debian don't support bonding out of
+the box. The ifenslave-2.6 package should be installed to provide bonding
+support.  Once installed, this package will provide bond-* options to be used
+into /etc/network/interfaces.
+
+	Note that ifenslave-2.6 package will load the bonding module and use
+the ifenslave command when appropriate.
+
+Example Configurations
+----------------------
+
+In /etc/network/interfaces, the following stanza will configure bond0, in
+active-backup mode, with eth0 and eth1 as slaves.
+
+auto bond0
+iface bond0 inet dhcp
+	bond-slaves eth0 eth1
+	bond-mode active-backup
+	bond-miimon 100
+	bond-primary eth0 eth1
+
+If the above configuration doesn't work, you might have a system using
+upstart for system startup. This is most notably true for recent
+Ubuntu versions. The following stanza in /etc/network/interfaces will
+produce the same result on those systems.
+
+auto bond0
+iface bond0 inet dhcp
+	bond-slaves none
+	bond-mode active-backup
+	bond-miimon 100
+
+auto eth0

+each control. For example, in the case of a volume/mute cluster the 'is_new'
+flag of the mute control would be set if the user called VIDIOC_S_CTRL for
+mute only. If the user would call VIDIOC_S_EXT_CTRLS for both mute and volume
+controls, then the 'is_new' flag would be 1 for both controls.
+
+The 'is_new' flag is always 1 when called from v4l2_ctrl_handler_setup().
