sparse warns about context imbalance in any code
that uses HARD_TX_LOCK/UNLOCK - this is because it's
unable to determine that flags don't change so
lock and unlock are paired.

Seems easy enough to fix by adding __acquire/__release
calls.

Ulrik De Bie 428951161b ptp: gianfar: Use high resolution frequency method.
This patch depends on commit d8d2635419 ("ptp: Introduce a high
resolution frequency adjustment method.")

The gianfar devices offer a frequency resolution of about 0.46 ppb
(depends on actual value of tmr_add, for the calculation assumed
0x80000000). This patch lets users of the device benefit from the increased
frequency resolution when tuning the clock. Thanks to the rounding the
maximum error between the requested frequency and the applied frequency
will then be about 0.23 ppb.

Tested on a v3.3.8 kernel on a real gianfar device. Verified compilation
on net-next (currently at v4.9-rc5).

Jon Paul Maloy 6998cc6ec2 tipc: resolve connection flow control compatibility problem
In commit 10724cc7bb ("tipc: redesign connection-level flow control")
we replaced the previous message based flow control with one based on
1k blocks. In order to ensure backwards compatibility the mechanism
falls back to using message as base unit when it senses that the peer
doesn't support the new algorithm. The default flow control window,
i.e., how many units can be sent before the sender blocks and waits
for an acknowledge (aka advertisement) is 512. This was tested against
the previous version, which uses an acknowledge frequency of on ack per
256 received message, and found to work fine.

However, we missed the fact that versions older than Linux 3.15 use an
acknowledge frequency of 512, which is exactly the limit where a 4.6+
sender will stop and wait for acknowledge. This would also work fine if
it weren't for the fact that if the first sent message on a 4.6+ server
side is an empty SYNACK, this one is also is counted as a sent message,
while it is not counted as a received message on a legacy 3.15-receiver.
This leads to the sender always being one step ahead of the receiver, a
scenario causing the sender to block after 512 sent messages, while the
receiver only has registered 511 read messages. Hence, the legacy
receiver is not trigged to send an acknowledge, with a permanently
blocked sender as result.

We solve this deadlock by simply allowing the sender to send one more
message before it blocks, i.e., by a making minimal change to the
condition used for determining connection congestion.

====================
mlxsw: traps, trap groups and policers

Nogah says:

For a packet to be sent from the HW to the cpu, it needs to be trapped.
For a trap to be activate it should be assigned to a trap group.
Those trap groups can have policers, to limit the packet rate (the max
number of packets that can be sent to the cpu in a time slot, the rest
will be discarded) or the data rate (the same, but the count is not by the
number of packets but by their total length in bytes).

This patchset rearrange the trap setting API, re-write the traps and the
trap groups list in spectrum and assign them policers.

Nogah Frankel 9148e7cf73 mlxsw: spectrum: Add policers for trap groups
Configure policers and connect them to trap groups.

While many trap groups share policer's configuration they don't share
the actual policer because each trap group represents a different
flow / protocol and we don't want one of them to be able to exceed its
rate on behalf of another.
For example, if STP and LLDP gets to send 128 packets/sec each, if we
put them in one 256 packets/sec policer, one can send 200 packets while
the other only 50.

Note that IP2ME covers lots of flows, so it's limit is set to match the
cpu ability to handle data.

Nogah Frankel 117b0dad2d mlxsw: Create a different trap group list for each device
Trap groups can be used to control traps priority, both in terms of
which trap "wins" if a packet matches two traps (priority) and in terms
of packets from which trap group will be scheduled to the cpu first (tc).
They can also be used to set rate limiters (policers) on them (will be
added in the next patches).

Currently, we support two trap groups. In Spectrum we want a better
resolution, so every protocol / flow will have a different trap group,
so we can control its parameters separately. Once the policers will be
implemented, it will also allow us limit the rate of each protocol by
itself.

This patch change the trap group list to include:
* the emad trap group, which is shared for all the devices.
* Switchx2's trap groups, which are a copy of the current trap groups.
* Spectrum's new trap groups, in order to match the above guidelines.
(Switchib is using only the emad trap group, so it require no changes).

This patch also includes new configuration for Spectrum's trap groups,
with primary priority order within them.

Nogah Frankel 579c82e4c5 mlxsw: Change trap groups setting
Trap groups have many options which we currently set to default values.
In the next patches we will use many of them with non-default values.

Some of these options have no default value, so this patch sets them as
params for the trap group set function. Others almost always use the same
values, so the set function will use this default values. In the rare cases
when they will need to be with other values, these values can be set
directly (using the macros for fields in registers).

Parameters without default value:
TC - the traffic class for packets that hit this trap group.
    (old default is the max tc)
priority - if one packet hits multiple trap groups, the group with the
	   higher priority will "catch" it. (old default is 0)
policer - limit rate policer (old default is disabled)

Default parameters:
swid - switch id, relevant for the emad trap only, ignored on Spectrum.
       (new default is 0)
rdq - CPU receive descriptor queue (new default is identical to trap
      group id)

Nogah Frankel 0791051c43 mlxsw: core: Create a generic function to register / unregister traps
We have 2 types of HW traps to handle, rx traps and events.
The registration workflow for both is very similar. So it only make
sense to create one function to handle both.

This patch creates a struct to hold the data for both cases. It also
creates a registration and an un-registration functions that get this
generic struct as input.

Arnd Bergmann e8f967c3d8 mvpp2: use correct size for memset
gcc-7 detects a short memset in mvpp2, introduced in the original
merge of the driver:

drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_cls_init':
drivers/net/ethernet/marvell/mvpp2.c:3296:2: error: 'memset' used with length equal to number of elements without multiplication by element size [-Werror=memset-elt-size]

The result seems to be that we write uninitialized data into the
flow table registers, although we did not get any warning about
that uninitialized data usage.

Using sizeof() lets us initialize then entire array instead.

Jon Paul Maloy d876a4d2af tipc: improve sanity check for received domain records
In commit 35c55c9877 ("tipc: add neighbor monitoring framework") we
added a data area to the link monitor STATE messages under the
assumption that previous versions did not use any such data area.

For versions older than Linux 4.3 this assumption is not correct. In
those version, all STATE messages sent out from a node inadvertently
contain a 16 byte data area containing a string; -a leftover from
previous RESET messages which were using this during the setup phase.
This string serves no purpose in STATE messages, and should no be there.

Unfortunately, this data area is delivered to the link monitor
framework, where a sanity check catches that it is not a correct domain
record, and drops it. It also issues a rate limited warning about the
event.

Since such events occur much more frequently than anticipated, we now
choose to remove the warning in order to not fill the kernel log with
useless contents. We also make the sanity check stricter, to further
reduce the risk that such data is inavertently admitted.

Jon Paul Maloy f79675563a tipc: fix compatibility bug in link monitoring
commit 817298102b ("tipc: fix link priority propagation") introduced a
compatibility problem between TIPC versions newer than Linux 4.6 and
those older than Linux 4.4. In versions later than 4.4, link STATE
messages only contain a non-zero link priority value when the sender
wants the receiver to change its priority. This has the effect that the
receiver resets itself in order to apply the new priority. This works
well, and is consistent with the said commit.

However, in versions older than 4.4 a valid link priority is present in
all sent link STATE messages, leading to cyclic link establishment and
reset on the 4.6+ node.

We fix this by adding a test that the received value should not only
be valid, but also differ from the current value in order to cause the
receiving link endpoint to reset.
