mvneta: SGMII-based in-band link state signaling
Currently the fixed-link DT binding is pre-configured and
cannot be changed in run-time. This means the cable unplug
events are not being detected, and the link parameters can't
be negotiated.
The following patches are needed when mvneta is used
in fixed-link mode (without MDIO).
They add an API to fixed_phy that allows to update
status, and use that API in the mvneta driver when parsing
the SGMII in-band status.
There is also another implementation that doesn't add any API
and does everything in mvneta driver locally:
https://lkml.org/lkml/2015/3/31/327

mvneta: implement SGMII-based in-band link state signaling
When MDIO bus is unavailable (common setup for SGMII), the in-band
signaling must be used to correctly track link state.
This patch enables the in-band status delivery for link state changes, namely:
- link up/down
- link speed
- duplex full/half
fixed_phy_update_state() is used to update phy status.

add fixed_phy_update_state() - update state of fixed_phy
Currently fixed_phy uses a callback to periodically poll the link state.
This patch adds the fixed_phy_update_state() API.
It solves the following problems:
- On link state interrupt, MAC driver can't update status.
Instead it needs to provide the callback to periodically query
the HW about the link state. It is more efficient to update status
after interrupt.
- The callback needs to be unregistered before phy_disconnect(),
or otherwise it will be called with net_dev==NULL. phy_disconnect()
does not have enough info to unregister the callback automatically.
- The callback needs to be registered before of_phy_connect() to
avoid running with outdated state, but of_phy_connect() returns the
phy_device pointer, which is needed to register the callback. Registering
it before of_phy_connect() will therefore require a hack to get the
pointer earlier.
Overall, this addition makes the subsequent patch that implements
SGMII link status for mvneta, much cleaner.

jhash: Update jhash_[321]words functions to use correct initval
Looking over the implementation for jhash2 and comparing it to jhash_3words
I realized that the two hashes were in fact very different. Doing a bit of
digging led me to "The new jhash implementation" in which lookup2 was
supposed to have been replaced with lookup3.
In reviewing the patch I noticed that jhash2 had originally initialized a
and b to JHASH_GOLDENRATIO and c to initval, but after the patch a, b, and
c were initialized to initval + (length << 2) + JHASH_INITVAL. However the
changes in jhash_3words simply replaced the initialization of a and b with
JHASH_INITVAL.
This change corrects what I believe was an oversight so that a, b, and c in
jhash_3words all have the same value added consisting of initval + (length
<< 2) + JHASH_INITVAL so that jhash2 and jhash_3words will now produce the
same hash result given the same inputs.

Mitch provides a fix to prevent a malicious or buggy VF driver from
sending an invalid index into the VSI array which could panic the host.
Cleans up the code where a function was moved, but the message did
not follow. Adds protection to the VLAN filter list, same as the
MAC filter list, to protect from corruption if the watchdog happens
to run at the same time as a VLAN filter is being added/deleted.
Jesse changes several memcpy() statements to struct assignments which
are type safe and preferable. Fixed a bug when skb allocation fails,
where we should not continue using the skb pointer. Also fixed a void
function in FCoE which should not be returning anything.
Greg fixes both i40e and i40evf to set the Ethernet protocol correctly

tipc: simplify link mtu negotiation
When a link is being established, the two endpoints advertise their
respective interface MTU in the transmitted RESET and ACTIVATE messages.
If there is any difference, the lower of the two MTUs will be selected
for use by both endpoints.
However, as a remnant of earlier attempts to introduce TIPC level
routing. there also exists an MTU discovery mechanism. If an intermediate
node has a lower MTU than the two endpoints, they will discover this
through a bisectional approach, and finally adopt this MTU for common use.
Since there is no TIPC level routing, and probably never will be,
this mechanism doesn't make any sense, and only serves to make the
link level protocol unecessarily complex.
In this commit, we eliminate the MTU discovery algorithm,and fall back
to the simple MTU advertising approach. This change is fully backwards
compatible.

tipc: eliminate delayed link deletion at link failover
When a bearer is disabled manually, all its links have to be reset
and deleted. However, if there is a remaining, parallel link ready
to take over a deleted link's traffic, we currently delay the delete
of the removed link until the failover procedure is finished. This
is because the remaining link needs to access state from the reset
link, such as the last received packet number, and any partially
reassembled buffer, in order to perform a successful failover.
In this commit, we do instead move the state data over to the new
link, so that it can fulfill the procedure autonomously, without
accessing any data on the old link. This means that we can now
proceed and delete all pertaining links immediately when a bearer
is disabled. This saves us from some unnecessary complexity in such
situations.
We also choose to change the confusing definitions CHANGEOVER_PROTOCOL,
ORIGINAL_MSG and DUPLICATE_MSG to the more descriptive TUNNEL_PROTOCOL,
FAILOVER_MSG and SYNCH_MSG respectively.

tipc: drop tunneled packet duplicates at reception
In commit
8b4ed8634f8b3f9aacfc42b4a872d30c36b9e255
("tipc: eliminate race condition at dual link establishment")
we introduced a parallel link synchronization mechanism that
guarentees sequential delivery even for users switching from
an old to a newly established link. The new mechanism makes it
unnecessary to deliver the tunneled duplicate packets back to
the old link, as we are currently doing. It is now sufficient
to use the last tunneled packet's inner sequence number as
synchronization point between the two parallel links, whereafter
it can be dropped.
In this commit, we drop the duplicate packets arriving on the new
link, after updating the synchronization point at each new arrival.
Although it would now have been sufficient for the other endpoint
to only tunnel the last packet in its send queue, and not the
entire queue, we must still do this to maintain compatibility
with older nodes.
This commit makes it possible to get rid if some complex
interaction between the two parallel links.

====================
Remove iflink field from the net_device structure
The first goal of this series was to advertise the veth peer via the IFLA_LINK
attribute, but iflink was not ready for network namespaces.
The iflink of an interface should be set to its ifindex for a physical interface
and to another value (0 if not relevant) for a virtual interface.
This was not the case for some interfaces, like vxlan, bond, or bridge for
example.
There is also a risk, if the targeted interface moves to another netns, that the
ifindex changes without updating corresponding iflink fields (eg. vlan).
Moving the management of this property into virtual interface drivers allows to
better handle this last case because most of virtual interface drivers have a
pointer to the link netdevice.
Anyway, dev->iflink value was always a copy of some internal data of the virtual
interface driver, thus let's use these internal data directly.
So, this series removes the iflink field and let the drivers manage it.
Only the last patch was present in the v1, but I fully rework it.

The goal of this patch is to prepare the removal of the iflink field. It
introduces a new ndo function, which will be implemented by virtual interfaces.

Merge branch 'dsa-next'
Andrew Lunn says:
====================
DSA Mavell drivers refactoring and cleanup
v1->v2:
* Add missing signed-of-by: For patches authored by Guenter Roeck.
* Add Reviewed by from Guenter Roack to patch #5.
This is a collection of patches again net-next from today containing
refactoring and consolidate of code, cleanups and using #define's to
replace register numbers.
Patch #1 Swaps the 6131 driver to use the consolidated setup code.
Patch #2 Moves the Switch IDs used during probe into a central
location. We need these later so that we can differentiate
the different features the devices have.
Patch #3 Makes the 6131 driver set the number of ports in the private
state structure. It then uses this, rather than hard coded
maximum number of ports.
Patch #4 Similar to Patch #3, but for the 6123_61_65 driver.
Patch #5 Similar to Patch #3, and #4, but for all the remaining
drivers. This greatly increases the similarity of the code
between drivers, allow further patches to consolidate the
duplicated code.
Patch #6 Consolidate the switch reset code, which has two minor
variants. Removes around 35 lines per driver.
Patch #7 Moves phy page access functions out of the 6352 driver into
the shared code. Currently only the 6352 driver uses this,
but it is likely other devices will come along wanting this
functionality.
Patch #8 Consolidates the code used to access phy registers. Removes
around 40 lines of code per driver.
Patch #9 Fixes missing mutex locking in the EEE code, and refactors
the code a bit to make it more understandable with respect to
locks.
Patch #10 Consolidates reading statistics. This is very similar code
for all devices, but the number of available statistics
differ, which can be determined from the product ID. Removes
around 65 lines per driver.
Patch #11 Add #defines for registers, and bits within the
registers. For the moment, this is limited to the shared
code. The individual drivers will be converted once the
remaining duplicated code is consolidated
Patch #12 Fix broken statistic counters on the 6172. The 6352 family
requires the port number is poked into a different set of
bits in the register compared to other devices.
Many thanks to Guenter Roeck for repeatedly reviewing the patches and
testing them on his hardware.

net: dsa: mv88e6xxx: Fix stats counters for 6352 family
The statistic counters for the mv88e6172 never worked. This device is
a member of the 6352 family of chips, which has a slightly different
layout of the register used for capturing statistics. Add support for
detecting this family and poking the port in the right place in the
register.
