+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
+iface eth0 inet manual
+ bond-master bond0
+ bond-primary eth0 eth1
+
+auto eth1
+iface eth1 inet manual
+ bond-master bond0
+ bond-primary eth0 eth1
+
+For a full list of bond-* supported options in /etc/network/interfaces and some
+more advanced examples tailored to you particular distros, see the files in
+/usr/share/doc/ifenslave-2.6.

+ Support for CAN cards from Softing Gmbh & some cards
+ from Vector Gmbh.
+ Softing Gmbh CAN cards come with 1 or 2 physical busses.
+ Those cards typically use Dual Port RAM to communicate
+ with the host CPU. The interface is then identical for PCI
+ and PCMCIA cards. This driver operates on a platform device,
+ which has been created by softing_cs or softing_pci driver.
+ Warning:
+ The API of the card does not allow fine control per bus, but
+ controls the 2 busses on the card together.
+ As such, some actions (start/stop/busoff recovery) on 1 bus
+ must bring down the other bus too temporarily.

+ firmware version 4.6 (softing-fw-4.6-binaries.tar.gz)
