net: phy: Create sysfs reciprocal links for attached_dev/phydev

This patch series addresses a device topology shortcoming where a program
scanning /sys would not be able to establish a mapping between the network

There is currently no way for a program scanning /sys to know whether a
network device is attached to a particular PHY device, just like the PHY
device is not pointed back to its attached network device.

Create a symbolic link in the network device's namespace named "phydev"
which points to the PHY device and create a symbolic link in the PHY
device's namespace named "attached_dev" that points back to the network
device. These links are set up during phy_attach_direct() and removed
during phy_detach() for symetry.

mlxsw: Support firmware flash

Add support for device firmware flash on mlxsw spectrum. The firmware files
are expected to be in the Mellanox Firmware Archive version 2 (MFA2)
format.

The firmware flash is triggered on driver initialization time if the device
firmware version does not meet the minimum firmware version supported by
the driver.

Currently, to activate the newly flashed firmware, the user needs to
reboot his system.

The first patch introduces the mlxfw module, which implements common logic
needed for the firmware flash process on Mellanox products, such as the
MFA2 format parsing and the firmware flash state machine logic. As the
module implements common logic which will be needed by various different
Mellanox drivers, it defines a set of callbacks needed to interact with the
specific device.

Patches 1-5 implement the needed mlxfw callbacks in the mlxsw spectrum
driver.

Patches 6 and 7 add boot-time firmware upgrade on the mlxsw spectrum
driver.

Patch 8 adds a fix needed for new firmware versions.

In new firmware versions, when configuring a {Port, VID} as a router

Make the spectrum module check the current device firmware version, and if

The mlxfw module is in charge of common logic needed to flash Mellanox
devices firmware, which consists of:
 - Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is
   the format used to store the Mellanox firmware. The MFA2 format file can
   hold firmware for many different silicon variants, differentiated by a
   unique ID called PSID. In addition, the MFA2 file data section is
   compressed using xz compression to save both file-system space and
   memory at extraction time.
 - Implement the firmware flash state machine logic, which is a common
   logic for Mellanox products needed to flash the firmware to the device.

As the module is shared between different Mellanox products, it defines a
set of callbacks to be implemented by the specific driver for hardware
interaction.

Support network namespacing in AF_RXRPC with the following changes:

 (1) All the local endpoint, peer and call lists, locks, counters, etc. are
     moved into the per-namespace record.

 (2) All the connection tracking is moved into the per-namespace record
     with the exception of the client connection ID tree, which is kept
     global so that connection IDs are kept unique per-machine.

 (3) Each namespace gets its own epoch.  This allows each network namespace
     to pretend to be a separate client machine.

 (4) The /proc/net/rxrpc_xxx files are now called /proc/net/rxrpc/xxx and
     the contents reflect the namespace.

fs/afs/ should be okay with this patch as it explicitly requires the current
net namespace to be init_net to permit a mount to proceed at the moment.  It
will, however, need updating so that cells, IP addresses and DNS records are

net-next: stmmac: rework the speed selection

The current stmmac_adjust_link() part which handle speed have
some if (has_platform) code and my dwmac-sun8i will add more of them.

So we need to handle better speed selection.
Moreover the struct link member speed and port are hard to guess their
purpose. And their unique usage are to be combined for writing speed.

My first try was to create an adjust_link() in stmmac_ops but it duplicate some code

The current solution is to have direct value for 10/100/1000 and a mask for them.

The first 4 patchs fix some minor problem found in stmmac_adjust_link() and reported by Florian Fainelli in my previous serie.
The last patch is the real work.

This series is tested on cubieboard2 (dwmac1000) and opipc (dwmac-sun8i).

- Added the patch #4 "Convert old_link to bool" as suggested by Joe Perches
- Changed the speedmask

Changes since v2:
- Use true/false for new_state in patch #1

directly without using the struct link. This patch convert also their
