+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

+What:   noswapaccount kernel command line parameter
+When:   2.6.40
+Why:    The original implementation of memsw feature enabled by
+        CONFIG_CGROUP_MEM_RES_CTLR_SWAP could be disabled by the noswapaccount
+        kernel parameter (introduced in 2.6.29-rc1). Later on, this decision
+        turned out to be not ideal because we cannot have the feature compiled
+        in and disabled by default and let only interested to enable it
+        (e.g. general distribution kernels might need it). Therefore we have
+        added swapaccount[=0|1] parameter (introduced in 2.6.37) which provides
+        the both possibilities. If we remove noswapaccount we will have
+        less command line parameters with the same functionality and we
+        can also cleanup the parameter handling a bit ().

-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.

+          Support for PCMCIA cards from Softing Gmbh & some cards
+          from Vector Gmbh.
+          You need firmware for these, which you can get at
+          http://developer.berlios.de/projects/socketcan/
+          This version of the driver is written against
+          firmware version 4.6 (softing-fw-4.6-binaries.tar.gz)
+          In order to use the card as CAN device, you need the Softing generic
+          support too.
