This patch adds documentation for the MSCAN OF device bindings for

The main differences compared to the MSCAN on the MPC5200 are:
- More flexibility in choosing the CAN source clock and frequency:
Three different clock sources can be selected: "ip", "ref" or "sys".
For the latter two, a clock divider can be defined as well. If the
clock source is not specified by the device tree, we first try to
find an optimal CAN source clock based on the system clock. If that
is not possible, the reference clock will be used.
- The behavior of bus-off recovery is configurable:
To comply with the usual handling of Socket-CAN bus-off recovery,
"recovery on request" is selected (instead of automatic recovery).
Note that only MPC5121 Rev. 2 and later is supported.

The start_xmit function of the MSCAN Driver did return improperly if
the CAN dlc check failed (skb not freed and invalid return code). This
patch adds a proper check of the frame lenght and data size and returns
now correctly. The invalid skb packets are dropped silently as suggested
by David Miller in the thread "[RFC] ndo_validate_skb: Let the netdev
check a valid skb content" on the netdev mailing list.
Furthermore, a typo has been fixed.

General cleanup of the ep93xx_eth driver.
1) Use pr_fmt() to prefix the module name and __func__ to the error
messages.
2) <linux/io.h> instead of <asm/io.h>
3) <mach/hardware.h> instead of <mach/ep93xx-regs.h> and <mach/platform.h>
4) Move the ep93xx_mdio_read (and ep93xx_mdio_write) function to eliminate
the function prototype.
5) Change all the printk(<level> messages to pr_<level> and remove the
__func__ argument.
6) Use platform_get_{resource/irq} to get the platform resources and add
an error check.
7) Use resource_size() for request_mem_region() and ioremap().
8) Use %pM to print the MAC address at the end of the probe.
9) Use dev->dev_addr not data->dev_addr for the MAC argument because a
random address could be used if the platform does not supply one.
The message at the end of the probe is left as a printk since it displays
cleaner without the function name that would be displayed with pr_info().

The MSI-X table size needs to be properly set before pci_enable_msix()
is called. But on certain machines, the writes are delayed and the
MSI-X table size is incorrectly read. By reading the
BNX2_PCI_MSIX_CONTROL register, the writes are flushed and now
ensure that the MSI-X table is set correctly before MSI-X
is enable on the device.

The contents of /proc/net/dev is annoying to parse, because
it changes whether there is a space after the "ethX:" or not.
It depends upon the size of the "Receive bytes" counter,
if the number is below 7 digits, then there is whitespaces
else if the number is 8 digits or above there is no space
between the ":" and the number.
This patch changes the output to assure there is always a space
between the ":" and the number. Given that all existing userspace
application already need to handle the whitespaces, I see
no breakage of existing tools.

This is to be used together with switch technologies, like RFC3069,
that where the individual ports are not allowed to communicate with
each other, but they are allowed to talk to the upstream router. As
described in RFC 3069, it is possible to allow these hosts to
communicate through the upstream router by proxy_arp'ing.
This patch basically allow proxy arp replies back to the same
interface (from which the ARP request/solicitation was received).
Tunable per device via proc "proxy_arp_pvlan":
/proc/sys/net/ipv4/conf/*/proxy_arp_pvlan
This switch technology is known by different vendor names:
- In RFC 3069 it is called VLAN Aggregation.
- Cisco and Allied Telesyn call it Private VLAN.
- Hewlett-Packard call it Source-Port filtering or port-isolation.
- Ericsson call it MAC-Forced Forwarding (RFC Draft).

This patch fixes up a problem with found with commit
1f3c8804ac. The original change
overloaded null_or_orig, but doing that prevented any packet handlers
that were not tied to a specific device (i.e. ptype->dev == NULL) from
ever receiving any frames.
The null_or_orig variable cannot be overloaded, and must be kept as NULL
to prevent the frame from being ignored by packet handlers designed to
accept frames on any interface.
