The problem is caused by the incorrect handling of the parent inode's
i_nlink count for the dentry to be RENAME_EXCHANGED. There are 3 cases
to consider. Assume we want to RENAME_EXCHANGE struct dentry *a and
struct dentry *b, and inode_a is pointed to by dentry_a, inode_b is
pointed to by dentry_b:
1. If inode_a is a directory, but inode_b isn't, then we must decrease
the i_nlink count of old_dir_i, and increase the i_nlink of new_dir_i.
2. If inode_a isn't a directory, but inode_b is a directory, then we
must increase the i_nlink of old_dir_i, and decrease the i_nlink count
of new_dir_i.
3. If the types of inode_a and inode_b are the same, we don't change the
i_nlink for either old_dir_i or new_dir_i.

Switch to the common LED related status_led_blink_* functions in
set_state() as it's done in most of other targets.
Also, use "status_led_on" instead of "status_led_set_heartbeat"
and incorrect "status_led_set_on" in the "done" state.
Moreover, remove outdated comment from the script.

When the device name doesn't already contain "RouterBOARD", this patch adds
this string to the machine name.
Most NOR devices already have "RouterBOARD" in their hardware-stored device name,
but not all of them.
This patch also makes the code more robust against buffer overflows.

SMP state is generally affected by
- CONFIG_SMP build-time kernel configuration option and
- 'nosmp' runtime kernel commandline option
The SMP state within vpe-mt.c is determined by CONFIG_SMP option.
A runtime check is needed if VPE functionality
should be used with a kernel image that supports SMP.
This fix introduces a check for 'nosmp' command line option
if CONFIG_SMP kernel configuration option is enabled.
Note: This patch is needed to use lantiq FXS if CONFIG_MIPS_MT_SMP
(that activates CONFIG_SMP) is enabled within kernel configuration
and the 'nosmp' command line argument is given to disable SMP at runtime.
Without this patch CONFIG_MIPS_MT_SMP must be disabled before using FXS.
With this patch setting the 'nosmp' parameter is enough.
In general, concurrent usage of FXS and SMP
is incompatible and will cause kernel panics.

The available amount of coherent DMA memory is very limited. On Linux
4.4 this issue was worked around by increasing the pool size.
It turns out that using coherent memory here is completely unnecessary.
This change reworks the driver code to use kzalloc+dma_map_single
instead.

The Netgear WNDR4300, equipped with an Atheros AR8327 Gigabit Switch,
has two LEDs on each port for monitoring LAN activity, but it currently
only uses one. Fix the configuration to use both.
The patch provides this new configuration:
- green LED: 1 Gbps link, 4Hz blink frequency
- amber LED: 10/100 Mbps link. 4Hz for 100Mbps, 2Hz for 10Mbps

At now there is no general rule about what part of (or whole) machine
name string should be used for board name assignment/detection and every
target handles this in a different way.
For most of the boards in ar71xx we already use only part of the string,
generally without the vendor name.
This shortens wildcards patterns in case statement for board name
assignment, wherever possible (e.g. where it won't be misleading).

Be consistent and always use double quotes for case statement patterns,
as in other targets. With this approach it should be less confusing for
users adding support for new devices.
Also, be consistent with MikroTik boards wildcard pattern.

on the router.
- Enable telnet with link: http://192.168.1.1/setup.cgi?todo=debug
(login if required, default: admin password)

- Telnet 192.168.1.1 and login with "root"
- ls /mnt/shares/ to find out path of your USB disk. 'myUdisk' for
example.
- cd /mnt/shares/myUdisk
- mtd_write write rootfs.bin Rootfs
- mtd_write write kernel.bin Kernel

Using the lantiq,wan device tree property for one interface node and
the lantiq,switch device tree property for another interface node at
the same time was never intended/isn't supported at the moment.
The property is meant to be used in two phy operation mode where one
phy is assigned to an interface without lantiq,* device tree property
and the other phy is assigned to an interface with the lantiq,wan
device property to have two netdevs.
If both properties are used at the same time, the lantiq,wan interface
is shown as independent netdev but not able to operate independent. The
port needs to be managed via swconfig. These dependency is not obvious
and fooled already a lot of users.
Add a default WAN vlan for xrx200 devices having an ethernet WAN port
and remove the lantiq,wan device tree property. Leave it up to the user
to set the ethernet WAN port as default WAN interface or to use this
port as additional LAN port.

The two phy operation mode where one phy is assigned to an interface
without lantiq,* device tree property and the other phy is assigned to
an interface with the lantiq,wan device property was broken with the
multicast package leaks between vlans fixes.
Move the multicast packages relevant portmap settings to the condition
which handles multicast packages for better readability.
Replace the priv->port_map based port_map only for the interface which
has the lantiq,switch device tree property set, to allow tagged
multicast packages in two phy mode where the lantiq,switch device tree
property isn't used.

power-cycled by setting GPIO 0 to high/low.
* The D240 only needs the MT76x2 module, so update makefile to reflect this.
Note that until the default mt7620 target is updated, then kmod-mt76 (and thus
kmod-mt7603) will be selected by default.
