1What: /sys/devices/platform/at91_can/net/<iface>/mb0_id
2Date: January 2011
3KernelVersion: 2.6.38
4Contact: Marc Kleine-Budde <kernel@pengutronix.de>
5Description:
6 Value representing the can_id of mailbox 0.
7
8 Default: 0x7ff (standard frame)
9
10 Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
11 "AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the
12 contents of mailbox 0 may be send under certain
13 conditions (even if disabled or in rx mode).
14
15 The workaround in the errata suggests not to use the
16 mailbox and load it with an unused identifier.
17
18 In order to use an extended can_id add the
19 CAN_EFF_FLAG (0x80000000U) to the can_id. Example:
20
21 - standard id 0x7ff:
22 echo 0x7ff > /sys/class/net/can0/mb0_id
23
24 - extended id 0x1fffffff:
25 echo 0x9fffffff > /sys/class/net/can0/mb0_id

13303.5 Overriding Configuration for Special Cases 13353.5 Configuration with Interfaces Support
1336-----------------------------------------
1337
1338 This section applies to distros which use /etc/network/interfaces file
1339to describe network interface configuration, most notably Debian and it's
1340derivatives.
1341
1342 The ifup and ifdown commands on Debian don't support bonding out of
1343the box. The ifenslave-2.6 package should be installed to provide bonding
1344support. Once installed, this package will provide bond-* options to be used
1345into /etc/network/interfaces.
1346
1347 Note that ifenslave-2.6 package will load the bonding module and use
1348the ifenslave command when appropriate.
1349
1350Example Configurations
1351----------------------
1352
1353In /etc/network/interfaces, the following stanza will configure bond0, in
1354active-backup mode, with eth0 and eth1 as slaves.
1355
1356auto bond0
1357iface bond0 inet dhcp
1358 bond-slaves eth0 eth1
1359 bond-mode active-backup
1360 bond-miimon 100
1361 bond-primary eth0 eth1
1362
1363If the above configuration doesn't work, you might have a system using
1364upstart for system startup. This is most notably true for recent
1365Ubuntu versions. The following stanza in /etc/network/interfaces will
1366produce the same result on those systems.
1367
1368auto bond0
1369iface bond0 inet dhcp
1370 bond-slaves none
1371 bond-mode active-backup
1372 bond-miimon 100
1373
1374auto eth0
1375iface eth0 inet manual
1376 bond-master bond0
1377 bond-primary eth0 eth1
1378
1379auto eth1

1385more advanced examples tailored to you particular distros, see the files in
