ef7b8aa8ca can: m_can: factorize clock gating and ungating
This creates a function to ungate M_CAN clocks and another to gate the
same clocks, then swaps all gating/ungating code with their respective
function.

8a3f3f24a8 can: m_can: make m_can_start and m_can_stop symmetric
This moves clocks gating outside of the m_can_stop function as the
m_can_start function does not (and cannot, at least in current
implementation) ungate clocks. This way, both functions can now be used
symmetrically.

6a792e8158 can: m_can: move Message RAM initialization to function
To avoid possible ECC/parity checksum errors when reading an
uninitialized buffer, the entire Message RAM is initialized when probing
the driver. This initialization is done in the same function reading the
Device Tree properties.

This patch moves the RAM initialization to a separate function so it can
be called separately from device initialization from Device Tree.

====================
net: phy: marvell: Checkpatch cleanup

I will be contributing a few new features to the Marvell PHY driver
soon. Start by making the code mostly checkpatch clean. There should
not be any functional changes. Just comments set into the correct
format, missing blank lines, turn some comparisons around, and
refactoring to reduce indentation depth.

There is still one camel in the code, but it actually makes sense, so
leave it in piece.

e26925ec03 Merge branch 'tcp-TCP-TS-option-use-1-ms-clock'
Eric Dumazet says:

====================
tcp: TCP TS option use 1 ms clock

TCP Timestamps option is defined in RFC 7323

Traditionally on linux, it has been tied to the internal
'jiffy' variable, because it had been a cheap and good enough
generator.

Unfortunately some distros use HZ=250 or even HZ=100 leading
to not very useful TCP timestamps.

For TCP flows in the DC, Google has used usec resolution for more
than two years with great success [1].
RCVBUF autotuning is more precise.

This series converts tp->tcp_mstamp to a plain u64 value storing
a 1 usec TCP clock.

This choice will allow us to upstream the 1 usec TS option as
discussed in IETF 97.

Kathleen Nichols [2] and others advocate for 1ms TS clocks for
network analysis. (1ms being the lowest value supported by RFC 7323.)

9a568de481 tcp: switch TCP TS option (RFC 7323) to 1ms clock
TCP Timestamps option is defined in RFC 7323

Traditionally on linux, it has been tied to the internal
'jiffies' variable, because it had been a cheap and good enough
generator.

For TCP flows on the Internet, 1 ms resolution would be much better
than 4ms or 10ms (HZ=250 or HZ=100 respectively)

For TCP flows in the DC, Google has used usec resolution for more
than two years with great success [1]

Receive size autotuning (DRS) is indeed more precise and converges
faster to optimal window size.

This patch converts tp->tcp_mstamp to a plain u64 value storing
a 1 usec TCP clock.

This choice will allow us to upstream the 1 usec TS option as
discussed in IETF 97.

ec66eda82d tcp: introduce tcp_jiffies32
We abuse tcp_time_stamp for two different cases :

1) base to generate TCP Timestamp options (RFC 7323)

2) A 32bit version of jiffies since some TCP fields
   are 32bit wide to save memory.

Since we want in the future to have 1ms TCP TS clock,
regardless of HZ value, we want to cleanup things.

tcp_jiffies32 is the truncated jiffies value,
which will be used only in places where we want a 'host'
timestamp.

656aae4305 Merge branch 'net-sched-multichain-filters'
Jiri Pirko says:

====================
net: sched: introduce multichain support for filters

Currently, each classful qdisc holds one chain of filters.
This chain is traversed and each filter could be matched on, which
may lead to execution of list of actions. One of such action
could be "reclassify", which would "reset" the processing of the
filter chain.

So this filter chain could be looked at as a flat table.
Sometimes it is convenient for user to configure a hierarchy
of tables. Example usecase is encapsulation.

Hierarchy of tables is a common way how it is done in HW pipelines.
So it is much more convenient to offload this.

This patchset contains two major patches:
8/10 - This patch introduces the support for having multiple
       chains of filters.
10/10 - This patch adds new control action to allow going to specified chain

The rest of the patches are smaller or bigger depencies of those 2.
Please see individual patch descriptions for details.

Corresponding iproute2 patches are appended as a reply to this cover letter.

Simple example:
$ tc qdisc add dev eth0 ingress
$ tc filter add dev eth0 parent ffff: protocol ip pref 33 flower dst_mac 52:54:00:3d:c7:6d action goto chain 11
$ tc filter add dev eth0 parent ffff: protocol ip pref 22 chain 11 flower dst_ip 192.168.40.1 action drop
$ tc filter show dev eth0 root
filter parent ffff: protocol ip pref 33 flower chain 0
filter parent ffff: protocol ip pref 33 flower chain 0 handle 0x1
  dst_mac 52:54:00:3d:c7:6d
  eth_type ipv4
        action order 1: gact action goto chain 11
         random type none pass val 0
         index 2 ref 1 bind 1

filter parent ffff: protocol ip pref 22 flower chain 11
filter parent ffff: protocol ip pref 22 flower chain 11 handle 0x1
  eth_type ipv4
  dst_ip 192.168.40.1

in chain but rather reset to the first filter of the desired chain.

Instead of having only one filter per block, introduce a list of chains
for every block. Create chain 0 by default. UAPI is extended so the user
can specify which chain he wants to change. If the new attribute is not
specified, chain 0 is used. That allows to maintain backward
compatibility. If chain does not exist and user wants to manipulate with
it, new chain is created with specified index. Also, when last filter is
removed from the chain, the chain is destroyed.

it "tcf_block".

Helpers to get and put the blocks are provided to be called from
individual qdisc code. Also, the original filter_list pointers are left
in qdisc privs to allow the entry into tcf_block processing without any
added overhead of possible multiple pointer dereference on fast path.

e1e3ce6236 liquidio: fix insmod failure when multiple NICs are plugged in
When multiple liquidio NICs are plugged in, the first insmod of the PF
driver succeeds.  But after an rmmod, a subsequent insmod fails.  Reason is
during rmmod, the PF driver resets the Octeon of only one of the NICs; it
neglects to reset the Octeons of the other NICs.

Fix the insmod failure by adding the missing Octeon resets at rmmod.  Keep
a per-NIC refcount that indicates the number of active PFs in a given NIC.
When the refcount goes to zero, then reset the Octeon of that NIC.

631581bf46 Merge branch 'mlxsw-Preparations-for-restructuring'
Jiri Pirko says:

====================
mlxsw: Preparations for restructuring

This patchset doesn't introduce any functional changes and merely meant
to make the code base more receptive for upcoming restructuring.

The first six patches mainly shuffle code in order to reduce the scope of
structs that shouldn't be defined in the main driver header. Most of them
will be later expanded, so it makes sense to correctly place them now.

The last patches mostly simplify bridge-related functions, so that they
could be more easily modified later on.

45a4a16cdb mlxsw: spectrum: Default ports to non-virtual mode
In virtual mode, packets are classified to FIDs based on their ingress
port and VLAN whereas in non-virtual mode only the VLAN is taken into
account.

Currently ports are initialized to use virtual mode due to the presence
of the PVID vPort. However, we're going to transition ports between both
modes based on the FIDs they use and not merely based on the presence on
a VLAN upper. Therefore, during initialization, no mode will be
explicitly set.

Since the Programmer's Reference Manual (PRM) doesn't specify a default,
explicitly set the port to non-virtual mode and later transition the
port between both modes based on the FIDs it uses.

In a follow-up patchset, this step will be moved to the common FID core
where it logically belongs.

b02eae9b91 mlxsw: spectrum: Move PVID code to appropriate place
PVID is a port attribute and should therefore reside in the main driver
file and not the switchdev specific one.

7cbc4277c7 mlxsw: spectrum_switchdev: Don't batch learning operations
We no longer batch VLAN operations, so there's no need to set the
learning state for a range of VLANs.

Use a common function to set the learning state for a Port-VLAN, thereby
making the code saner more receptive for upcoming changes.

45bfe6b433 mlxsw: spectrum_switchdev: Don't batch STP operations
Simplify the code by using the common function that sets an STP state
for a Port-VLAN and remove the existing one that tries to batch it for
several VLANs.

This will help us in a follow-up patchset to introduce a unified
infrastructure for bridge ports, regardless if the bridge is VLAN-aware
or not.

fe9ccc785d mlxsw: spectrum_switchdev: Don't batch VLAN operations
switchdev's VLAN object has the ability to describe a range of VLAN IDs,
but this is only used when VLAN operations are done using the SELF flag,
which is something we would like to remove as it allows one to bypass
the bridge driver.

Do VLAN operations on a per-VLAN basis, thereby simplifying the code and
preparing it for refactoring in a follow-up patchset.
