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

2. Bonding Driver Options
=========================

You can configure bonding using either your distro's network
initialization scripts, or manually using either ifenslave or the
sysfs interface. Distros generally use one of two packages for the
network initialization scripts: initscripts or sysconfig. Recent
versions of these packages have support for bonding, while older
sysfs interface. Distros generally use one of three packages for the
network initialization scripts: initscripts, sysconfig or interfaces.
Recent versions of these packages have support for bonding, while older
versions do not.
We will first describe the options for configuring bonding for
distros using versions of initscripts and sysconfig with full or
partial support for bonding, then provide information on enabling
distros using versions of initscripts, sysconfig and interfaces with full
or partial support for bonding, then provide information on enabling
bonding without support from the network initialization scripts (i.e.,
older versions of initscripts or sysconfig).
If you're unsure whether your distro uses sysconfig or
initscripts, or don't know if it's new enough, have no fear.
If you're unsure whether your distro uses sysconfig,
initscripts or interfaces, or don't know if it's new enough, have no fear.
Determining this is fairly straightforward.
First, issue the command:
First, look for a file called interfaces in /etc/network directory.
If this file is present in your system, then your system use interfaces. See
Configuration with Interfaces Support.

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.
3.6 Overriding Configuration for Special Cases
----------------------------------------------
When using the bonding driver, the physical port which transmits a frame is
typically selected by the bonding driver, and is not relevant to the user or
system administrator. The output port is simply selected using the policies of
