c8715a8e9f ipmr: Add high byte of VIF ID to igmpmsg
Use the unused3 byte in struct igmpmsg to hold the high 8 bits of the
VIF ID.

If using more than 255 IPv4 multicast interfaces it is necessary to have
access to a VIF ID for cache reports that is wider than 8 bits, the VIF
ID present in the igmpmsg reports sent to mroute_sk was only 8 bits wide
in the igmpmsg header.  Adding the high 8 bits of the 16 bit VIF ID in
the unused byte allows use of more than 255 IPv4 multicast interfaces.

501cb00890 ipmr: Add route table ID to netlink cache reports
Insert the multicast route table ID as a Netlink attribute to Netlink
cache report notifications.

When multiple route tables are in use it is necessary to have a way to
determine which route table a given cache report belongs to when
receiving the cache report.

====================
Marvell PP2.2 PTP support

This series adds PTP support for PP2.2 hardware to the mvpp2 driver.
Tested on the Macchiatobin eth1 port.

Note that on the Macchiatobin, eth0 uses a separate TAI block from
eth1, and there is no hardware synchronisation between the two.

ce3497e207 net: mvpp2: ptp: add support for receive timestamping
Add support for receive timestamping. When enabled, the hardware adds
a timestamp into the receive queue descriptor for all received packets
with no filtering. Hence, we can only support NONE or ALL receive
filter modes.

The timestamp in the receive queue contains two bit sof seconds and
the full nanosecond timestamp. This has to be merged with the remainder
of the seconds from the TAI clock to arrive at a full timestamp before
we can convert it to a ktime for the skb hardware timestamp field.

8914197269 net: mvpp2: rename mis-named "link status" interrupt
The link interrupt is used for way more than just the link status; it
comes from a collection of units to do with the port. The Marvell
documentation describes the interrupt as "GOP port X interrupt".

Since we are adding PTP support, and the PTP interrupt uses this,
rename it to be more inline with the documentation.

This interrupt is also mis-named in the DT binding, but we leave that
alone.

b599a5b9e1 Merge branch 'devlink-show-controller-number'
Parav Pandit says:

====================
devlink show controller number

Currently a devlink instance that supports an eswitch handles eswitch
ports of two type of controllers.
(1) controller discovered on same system where eswitch resides.
This is the case where PCI PF/VF of a controller and devlink eswitch
instance both are located on a single system.
(2) controller located on external system.
This is the case where a controller is plugged in one system and its
devlink eswitch ports are located in a different system. In this case
devlink instance of the eswitch only have access to ports of the
controller.
However, there is no way to describe that a eswitch devlink port
belongs to which controller (mainly which external host controller).
This problem is more prevalent when port attribute such as PF and VF
numbers are overlapping between multiple controllers of same eswitch.
Due to this, for a specific switch_id, unique phys_port_name cannot
be constructed for such devlink ports.

This short series overcomes this limitation by defining two new
attributes.
(a) external: Indicates if port belongs to external controller
(b) controller number: Indicates a controller number of the port

Based on this a unique phys_port_name is prepared using controller
number.

phys_port_name construction using unique controller number is only
applicable to external controller ports. This ensures that for
non smartnic usecases where there is no external controller,
phys_port_name stays same as before.

Patch summary:
Patch-1 Added mlx5 driver to read controller number
Patch-2 Adds the missing comment for the port attributes
Patch-3 Move structure comments away from structure fields
Patch-4 external attribute added for PCI port flavours
Patch-5 Add controller number
Patch-6 Use controller number to build phys_port_name

---
Changelog:
v2->v3:
 - Updated diagram to get rid of controller 'A' and 'B'
 - Kept ports of single controller together in diagram
 - Updated diagram for pf1's VF and SF and its ports
v1->v2:
 - Added text diagram of multiple controllers
 - Updated example for a VF
 - Addressed comments from Jiri and Jakub
 - Moved controller number attribute to PCI port flavours
   This enables to better, hirerchical view with controller and its
    PF, VF numbers
 - Split 'external' and 'controller number' attributes as two
   different attributes
 - Merged mlx5_core driver to avoid compiliation break

66b17082d1 devlink: Use controller while building phys_port_name
Now that controller number attribute is available, use it when
building phsy_port_name for external controller ports.

An example devlink port and representor netdev name consist of controller
annotation for external controller with controller number = 1,
for a VF 1 of PF 0:

$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev ens2f0c1pf0vf1 flavour pcivf controller 1 pfnum 0 vfnum 1 external true splittable false
  function:
    hw_addr 00:00:00:00:00:00

$ devlink port show pci/0000:06:00.0/2 -jp
{
    "port": {
        "pci/0000:06:00.0/2": {
            "type": "eth",
            "netdev": "ens2f0c1pf0vf1",
            "flavour": "pcivf",
            "controller": 1,
            "pfnum": 0,
            "vfnum": 1,
            "external": true,
            "splittable": false,
            "function": {

            }
        }
    }
}

Controller number annotation is skipped for non external controllers to
maintain backward compatibility.

3a2d9588c4 devlink: Introduce controller number
A devlink port may be for a controller consist of PCI device.
A devlink instance holds ports of two types of controllers.
(1) controller discovered on same system where eswitch resides
This is the case where PCI PF/VF of a controller and devlink eswitch
instance both are located on a single system.
(2) controller located on external host system.
This is the case where a controller is located in one system and its
devlink eswitch ports are located in a different system.

When a devlink eswitch instance serves the devlink ports of both
controllers together, PCI PF/VF numbers may overlap.
Due to this a unique phys_port_name cannot be constructed.

For example in below such system controller-0 and controller-1, each has
PCI PF pf0 whose eswitch ports can be present in controller-0.
These results in phys_port_name as "pf0" for both.
Similar problem exists for VFs and upcoming Sub functions.

bedd8d78ab net: phy: smsc: LAN8710/20: add phy refclk in support
Add support to specify the clock provider for the PHY refclk and don't
rely on 'magic' host clock setup. [1] tried to address this by
introducing a flag and fixing the corresponding host. But this commit
breaks the IRQ support since the irq setup during .config_intr() is
thrown away because the reset comes from the side without respecting the
current PHY state within the PHY library state machine. Furthermore the
commit fixed the problem only for FEC based hosts other hosts acting
like the FEC are not covered.

This commit goes the other way around to address the bug fixed by [1].
Instead of resetting the device from the side every time the refclk gets
(re-)enabled it requests and enables the clock till the device gets
removed. Now the PHY library is the only place where the PHY gets reset
to respect the PHY library state machine.

request, it causes a page fault due to absence of valid xfrmdev_ops.

Paul Barker says:

====================
ksz9477 dsa switch driver improvements

These changes were made while debugging the ksz9477 driver for use on a
custom board which uses the ksz9893 switch supported by this driver. The
patches have been runtime tested on top of Linux 5.8.4, I couldn't
runtime test them on top of 5.9-rc3 due to unrelated issues. They have
been build tested on top of net-next.

These changes can also be pulled from:

  https://gitlab.com/pbarker.dev/staging/linux.git
  tag: for-net-next/ksz-v3_2020-09-09

Changes from v2:

  * Fixed incorrect type in assignment error.
    Reported-by: kernel test robot <lkp@intel.com>

Changes from v1:

  * Rebased onto net-next.

  * Dropped unnecessary `#include <linux/printk.h>`.

  * Instead of printing the phy mode in `ksz9477_port_setup()`, modify
    the existing print in `ksz9477_config_cpu_port()` to always produce
    output and to be more clear.

5b79798090 net: dsa: microchip: Implement recommended reset timing
The datasheet for the ksz9893 and ksz9477 switches recommend waiting at
least 100us after the de-assertion of reset before trying to program the
device through any interface.

Also switch the existing msleep() call to usleep_range() as recommended
in Documentation/timers/timers-howto.rst. The 2ms range used here is
somewhat arbitrary, as long as the reset is asserted for at least 10ms
we should be ok.

To make switch detection more informative print the result of the

print the contents of the Chip ID registers as a 40-bit hex string.

As this detection is the first communication with the switch performed

Merge tag 'rxrpc-next-20200908' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

David Howells says:

====================
rxrpc: Allow more calls to same peer

Here are some development patches for AF_RXRPC that allow more simultaneous
calls to be made to the same peer with the same security parameters.  The
current code allows a maximum of 4 simultaneous calls, which limits the afs
filesystem to that many simultaneous threads.  This increases the limit to
16.

To make this work, the way client connections are limited has to be changed
(incoming call/connection limits are unaffected) as the current code
depends on queuing calls on a connection and then pushing the connection
through a queue.  The limit is on the number of available connections.

This is changed such that there's a limit[*] on the total number of calls
systemwide across all namespaces, but the limit on the number of client
connections is removed.

Once a call is allowed to proceed, it finds a bundle of connections and
tries to grab a call slot.  If there's a spare call slot, fine, otherwise
it will wait.  If there's already a waiter, it will try to create another
connection in the bundle, unless the limit of 4 is reached (4 calls per
connection, giving 16).

A number of things throttle someone trying to set up endless connections:

 - Calls that fail immediately have their conns deleted immediately,

 - Calls that don't fail immediately have to wait for a timeout,

 - Connections normally get automatically reaped if they haven't been used
   for 2m, but this is sped up to 2s if the number of connections rises
   over 900.  This number is tunable by sysctl.

[*] Technically two limits - kernel sockets and userspace rxrpc sockets are
    accounted separately.

cdd84a93da net: tc35815: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'tc35815_init_queues()' GFP_ATOMIC must be used
because it can be called from 'tc35815_restart()' where some spinlock are
taken.
The call chain is:
  tc35815_restart
    --> tc35815_clear_queues
      --> tc35815_init_queues

When memory is allocated in 'rr_init_one()' GFP_KERNEL can be used because
it is a probe function and no spinlock is taken in the between.

When memory is allocated in 'rr_open()' GFP_KERNEL can be used because
it is a '.ndo_open' function (see struct net_device_ops) and no spinlock is

'.ndo_open' functions are synchronized using the rtnl_lock() semaphore.
