fail_over_mac

Specifies whether active-backup mode should set all slaves to
the same MAC address (the traditional behavior), or, when
enabled, change the bond's MAC address when changing the
active interface (i.e., fail over the MAC address itself).

Fail over MAC is useful for devices that cannot ever alter
their MAC address, or for devices that refuse incoming
broadcasts with their own source MAC (which interferes with
the ARP monitor).

The down side of fail over MAC is that every device on the
network must be updated via gratuitous ARP, vs. just updating
a switch or set of switches (which often takes place for any
traffic, not just ARP traffic, if the switch snoops incoming
traffic to update its tables) for the traditional method. If
the gratuitous ARP is lost, communication may be disrupted.

When fail over MAC is used in conjuction with the mii monitor,
devices which assert link up prior to being able to actually
transmit and receive are particularly susecptible to loss of
the gratuitous ARP, and an appropriate updelay setting may be
required.

A value of 0 disables fail over MAC, and is the default. A
value of 1 enables fail over MAC. This option is enabled
automatically if the first slave added cannot change its MAC
address. This option may be modified via sysfs only when no
slaves are present in the bond.

This option was added in bonding version 3.2.0.
the same MAC address at enslavement (the traditional
behavior), or, when enabled, perform special handling of the
bond's MAC address in accordance with the selected policy.

Possible values are:

none or 0

This setting disables fail_over_mac, and causes
bonding to set all slaves of an active-backup bond to
the same MAC address at enslavement time. This is the
default.

active or 1

The "active" fail_over_mac policy indicates that the
MAC address of the bond should always be the MAC
address of the currently active slave. The MAC
address of the slaves is not changed; instead, the MAC
address of the bond changes during a failover.

This policy is useful for devices that cannot ever
alter their MAC address, or for devices that refuse
incoming broadcasts with their own source MAC (which
interferes with the ARP monitor).

The down side of this policy is that every device on
the network must be updated via gratuitous ARP,
vs. just updating a switch or set of switches (which
often takes place for any traffic, not just ARP
traffic, if the switch snoops incoming traffic to
update its tables) for the traditional method. If the
gratuitous ARP is lost, communication may be
disrupted.

When this policy is used in conjuction with the mii
monitor, devices which assert link up prior to being
able to actually transmit and receive are particularly
susecptible to loss of the gratuitous ARP, and an
appropriate updelay setting may be required.

follow or 2

The "follow" fail_over_mac policy causes the MAC
address of the bond to be selected normally (normally
the MAC address of the first slave added to the bond).
However, the second and subsequent slaves are not set
to this MAC address while they are in a backup role; a
slave is programmed with the bond's MAC address at
failover time (and the formerly active slave receives
the newly active slave's MAC address).

This policy is useful for multiport devices that
either become confused or incur a performance penalty
when multiple ports are programmed with the same MAC
address.


The default policy is none, unless the first slave cannot
change its MAC address, in which case the active policy is
selected by default.

This option may be modified via sysfs only when no slaves are
present in the bond.

This option was added in bonding version 3.2.0. The "follow"
policy was added in bonding version 3.3.0.

DM9000 Network driver
=====================

Copyright 2008 Simtec Electronics,
Ben Dooks <[email protected]> <[email protected]>


Introduction
------------

This file describes how to use the DM9000 platform-device based network driver
that is contained in the files drivers/net/dm9000.c and drivers/net/dm9000.h.

The driver supports three DM9000 variants, the DM9000E which is the first chip
supported as well as the newer DM9000A and DM9000B devices. It is currently
maintained and tested by Ben Dooks, who should be CC: to any patches for this
driver.


Defining the platform device
----------------------------

The minimum set of resources attached to the platform device are as follows:

1) The physical address of the address register
2) The physical address of the data register
3) The IRQ line the device's interrupt pin is connected to.

These resources should be specified in that order, as the ordering of the
two address regions is important (the driver expects these to be address
and then data).

An example from arch/arm/mach-s3c2410/mach-bast.c is:

static struct resource bast_dm9k_resource[] = {
[0] = {
.start = S3C2410_CS5 + BAST_PA_DM9000,
.end = S3C2410_CS5 + BAST_PA_DM9000 + 3,
.flags = IORESOURCE_MEM,
},
[1] = {
.start = S3C2410_CS5 + BAST_PA_DM9000 + 0x40,
.end = S3C2410_CS5 + BAST_PA_DM9000 + 0x40 + 0x3f,
.flags = IORESOURCE_MEM,
},
[2] = {
.start = IRQ_DM9000,
.end = IRQ_DM9000,
.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
}
};

static struct platform_device bast_device_dm9k = {
.name = "dm9000",
.id = 0,
.num_resources = ARRAY_SIZE(bast_dm9k_resource),
.resource = bast_dm9k_resource,
};

Note the setting of the IRQ trigger flag in bast_dm9k_resource[2].flags,
as this will generate a warning if it is not present. The trigger from
the flags field will be passed to request_irq() when registering the IRQ
handler to ensure that the IRQ is setup correctly.

This shows a typical platform device, without the optional configuration
platform data supplied. The next example uses the same resources, but adds
the optional platform data to pass extra configuration data:

static struct dm9000_plat_data bast_dm9k_platdata = {
.flags = DM9000_PLATF_16BITONLY,
};

static struct platform_device bast_device_dm9k = {
.name = "dm9000",
.id = 0,
.num_resources = ARRAY_SIZE(bast_dm9k_resource),
.resource = bast_dm9k_resource,
.dev = {
.platform_data = &bast_dm9k_platdata,
}
};

The platform data is defined in include/linux/dm9000.h and described below.


Platform data
-------------

Extra platform data for the DM9000 can describe the IO bus width to the
device, whether or not an external PHY is attached to the device and
the availability of an external configuration EEPROM.

The flags for the platform data .flags field are as follows:

DM9000_PLATF_8BITONLY

The IO should be done with 8bit operations.

DM9000_PLATF_16BITONLY

The IO should be done with 16bit operations.

DM9000_PLATF_32BITONLY

The IO should be done with 32bit operations.

DM9000_PLATF_EXT_PHY

The chip is connected to an external PHY.

DM9000_PLATF_NO_EEPROM

This can be used to signify that the board does not have an
EEPROM, or that the EEPROM should be hidden from the user.

DM9000_PLATF_SIMPLE_PHY

Switch to using the simpler PHY polling method which does not
try and read the MII PHY state regularly. This is only available
when using the internal PHY. See the section on link state polling
for more information.

The config symbol DM9000_FORCE_SIMPLE_PHY_POLL, Kconfig entry
"Force simple NSR based PHY polling" allows this flag to be
forced on at build time.


PHY Link state polling
----------------------

The driver keeps track of the link state and informs the network core
about link (carrier) availablilty. This is managed by several methods
depending on the version of the chip and on which PHY is being used.

For the internal PHY, the original (and currently default) method is
to read the MII state, either when the status changes if we have the
necessary interrupt support in the chip or every two seconds via a
periodic timer.

To reduce the overhead for the internal PHY, there is now the option
of using the DM9000_FORCE_SIMPLE_PHY_POLL config, or DM9000_PLATF_SIMPLE_PHY
platform data option to read the summary information without the
expensive MII accesses. This method is faster, but does not print
as much information.

When using an external PHY, the driver currently has to poll the MII
link status as there is no method for getting an interrupt on link change.


DM9000A / DM9000B
-----------------

These chips are functionally similar to the DM9000E and are supported easily
by the same driver. The features are:

1) Interrupt on internal PHY state change. This means that the periodic
polling of the PHY status may be disabled on these devices when using
the internal PHY.

2) TCP/UDP checksum offloading, which the driver does not currently support.


ethtool
-------

The driver supports the ethtool interface for access to the driver
state information, the PHY state and the EEPROM.
