99b981f431 net: dsa: sja1105: fix port mirroring for P/Q/R/S
The dynamic configuration interface for the General Params and the L2
Lookup Params tables was copy-pasted between E/T devices and P/Q/R/S
devices. Nonetheless, these interfaces are bitwise different.

The driver is using dynamic reconfiguration of the General Parameters
table for the port mirroring feature, which was therefore broken on
P/Q/R/S.

Note that this patch can't be backported easily very far to stable trees
(since it conflicts with some other development done since the
introduction of the driver). So the Fixes: tag is purely informational.

53bd63afbd net: dsa: sja1105: suppress -Wmissing-prototypes in sja1105_static_config.c
Newer compilers complain with W=1 builds that there are non-static
functions defined in sja1105_static_config.c that don't have a
prototype, because their prototype is defined in sja1105.h which this
translation unit does not include.

I don't entirely understand what is the point of these warnings, since
in principle there's nothing wrong with that. But let's move the
prototypes to a header file that _is_ included by
sja1105_static_config.c, since that will make these warnings go away.

aef31718a9 net: dsa: sja1105: avoid invalid state in sja1105_vlan_filtering
Be there 2 switches spi/spi2.0 and spi/spi2.1 in a cross-chip setup,
both under the same VLAN-filtering bridge, both in the
SJA1105_VLAN_BEST_EFFORT state.

If we try to change the VLAN state of one of the switches (to
SJA1105_VLAN_FILTERING_FULL) we get the following error:

devlink dev param set spi/spi2.1 name best_effort_vlan_filtering value
false cmode runtime
[   38.325683] sja1105 spi2.1: Not allowed to overcommit frame memory.
               L2 memory partitions and VL memory partitions share the
               same space. The sum of all 16 memory partitions is not
               allowed to be larger than 929 128-byte blocks (or 910
               with retagging). Please adjust
               l2-forwarding-parameters-table.part_spc and/or
               vl-forwarding-parameters-table.partspc.
[   38.356803] sja1105 spi2.1: Invalid config, cannot upload

This is because the spi/spi2.1 switch doesn't support tagging anymore in
the SJA1105_VLAN_FILTERING_FULL state, so it doesn't need to have any
retagging rules defined. Great, so it can use more frame memory
(retagging consumes extra memory).

But the built-in low-level static config checker from the sja1105 driver
says "not so fast, you've increased the frame memory to non-retagging
values, but you still kept the retagging rules in the static config".

So we need to rebuild the VLAN table immediately before re-uploading the
static config, operation which will take care, based on the new VLAN
state, of removing the retagging rules.

c223c7f22c Merge branch 'remove-kernel_setsockopt-v4'
Christoph Hellwig says:

====================
remove kernel_setsockopt v4

now that only the dlm calls to sctp are left for kernel_setsockopt,
while we haven't really made much progress with the sctp setsockopt
refactoring, how about this small series that splits out a
sctp_setsockopt_bindx_kernel that takes a kernel space address array
to share more code as requested by Marcelo.  This should fit in with
whatever variant of the refator of sctp setsockopt we go with, but
just solved the immediate problem for now.

Changes since v3:
 - dropped all the merged patches, just sctp setsockopt left now
 - factor out a new sctp_setsockopt_bindx_kernel helper instead of
   duplicating a small amount of logic

Changes since v2:
 - drop the separately merged kernel_getopt_removal
 - drop the sctp patches, as there is conflicting cleanup going on
 - add an additional ACK for the rxrpc changes

Changes since v1:
 - use ->getname for sctp sockets in dlm
 - add a new ->bind_add struct proto method for dlm/sctp
 - switch the ipv6 and remaining sctp helpers to inline function so that
   the ipv6 and sctp modules are not pulled in by any module that could
   potentially use ipv6 or sctp connections
 - remove arguments to various sock_* helpers that are always used with
   the same constant arguments

c0425a4249 net: add a new bind_add method
The SCTP protocol allows to bind multiple address to a socket.  That
feature is currently only exposed as a socket option.  Add a bind_add
method struct proto that allows to bind additional addresses, and
switch the dlm code to use the method instead of going through the
socket option from kernel space.

We need to call phy_restore_page() even if phy_select_page() fails.
Otherwise we are holding the phy_lock_mdio_bus() lock.  This requirement

2684bda347 net: phy: mscc: fix PHYs using the vsc8574_probe
PHYs using the vsc8574_probe fail to be initialized and their
config_init return -EIO leading to errors like:
"could not attach PHY: -5".

This is because when the conversion of the MSCC PHY driver to use the
shared PHY package helpers was done, the base address retrieval and the
base PHY read and write helpers in the driver were modified. In
particular, the base address retrieval logic was moved from the
config_init to the probe. But the vsc8574_probe was forgotten. This
patch fixes it.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2020-05-28

This series contains updates to e1000, e1000e, igc, igb, ixgbe and i40e.

Takashi Iwai, from SUSE, replaces some uses of snprintf() with
scnprintf() since the succeeding calls may go beyond the given buffer
limit in i40e.

Jesper Dangaard Brouer fixes up code comments in i40e_xsk.c

Xie XiuQi, from Huawei, fixes a signed-integer-overflow warning ixgbe
driver.

Jason Yan, from Huawei, converts '==' expression to bool to resolve
warnings, also fixed a warning for assigning 0/1 to a bool variable in
the ixgbe driver.  Converts functions that always return 0 to void in the
igb and i40e drivers.

YueHaibing, from Hauwei, cleans up dead code in ixgbe driver.

Sasha cleans up more dead code which is not used in the igc driver.
Added receive error counter to reflect the total number of non-filtered
packets received with errors.  Fixed a register define name to properly
reflect the register address being used.

Andre updates the igc driver to reject NFC rules that have multiple
matches, which is not supported in i225 devices.  Updates the total
number of NFC rules supported and added a code comment to explain what
is supported.

Punit Agrawal, from Toshiba, relaxes the condition to trigger a reset
for ME, which was leading to inconsistency between the state of the
hardware as expected by the driver in e1000e.

Hari, from the Linux community, cleaned up a code comment in the e1000
driver.
