ed193ece26 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.

dff29b1a88 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.

2da7142516 tipc: drop tunneled packet duplicates at reception
In commit 8b4ed8634f
("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.

Granular QoS for VFs, where for the time being only max rate is supported.

Muhammad added support for setting rx-fcs and rx-all through ethtool,
and Ido did the interface identify work.

Last, add Ido as a maintainer for the mlx4 Ethernet driver!

Some of next week is the Passover holiday here and I will be

====================
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.

7a66bbc96c net: remove iflink field from struct net_device
Now that all users of iflink have the ndo_get_iflink handler available, it's
possible to remove this field.

By default, dev_get_iflink() returns the ifindex of the interface.

a54acb3a6f dev: introduce dev_get_iflink()
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.

There is no functional change into this patch. All readers of iflink field
now call dev_get_iflink().

033f46b3c1 crypto: algif - explicitly mark end of data
After the TX sgl is expanded we need to explicitly mark end of data
at the last buffer that contains data.

Changes in v2
 - use type 'bool' and true/false for 'mark'.

====================
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 .

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  Swaps the 6131 driver to use the consolidated setup code.

Patch  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  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  Similar to Patch , but for the 6123_61_65 driver.

Patch  Similar to Patch , and , 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  Consolidate the switch reset code, which has two minor
         variants. Removes around 35 lines per driver.

Patch  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  Consolidates the code used to access phy registers. Removes
         around 40 lines of code per driver.

Patch  Fixes missing mutex locking in the EEE code, and refactors
         the code a bit to make it more understandable with respect to
         locks.

Patch  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  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  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.

f3a8b6b6a1 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.
