net: bcmgenet: move clk_wol management to bcmgenet_wol
The GENET_POWER_WOL_MAGIC power up and power down code configures
the device for WoL when suspending and disables the WoL logic when
resuming. It makes sense that this code should also manage the WoL
clocking.
This commit consolidates the logic and moves it earlier in the
resume sequence.
Since the clock is now only enabled if WoL is successfully entered
the wol_active flag is introduced to track that state to keep the
clock enables and disables balanced in case a suspend is aborted.
The MPD_EN hardware bit can't be used because it can be cleared
when the MAC is reset by a deep sleep.

net: bcmgenet: Fix WoL with password after deep sleep
Broadcom STB chips support a deep sleep mode where all register contents
are lost. Because we were stashing the MagicPacket password into some of
these registers a suspend into that deep sleep then a resumption would
not lead to being able to wake-up from MagicPacket with password again.
Fix this by keeping a software copy of the password and program it
during suspend.

net: bcmgenet: set Rx mode before starting netif
This commit explicitly calls the bcmgenet_set_rx_mode() function when
the network interface is started. This function is normally called by
ndo_set_rx_mode when the flags are changed, but apparently not when
the driver is suspended and resumed.
This change ensures that address filtering or promiscuous mode are
properly restored by the driver after the MAC may have been reset.

====================
net/smc: preparations for SMC-R link failover
This patch series prepares the SMC code for the implementation of SMC-R link
failover capabilities which are still missing to reach full compliance with
RFC 7609.
The code changes are separated into 65 patches which together form the new
functionality. I tried to create meaningful patches which allow to follow the
implementation.
Question: how to handle the remaining 52 patches? All of them are needed for
link failover to work and should make it into the same merge window.
Can I send them all together?
The SMC-R implementation will transparently make use of the link failover
feature when matching RoCE devices are available, no special setup is required.
All RoCE devices with the same PNET ID as the TCP device (hardware-defined or
user-defined via the smc_pnet tool) are candidates to get used to form a link
in a link group. When at least 2 RoCE devices are available on both
communication endpoints then a symmetric link group is formed, meaning the link
group has 2 independent links. If one RoCE device goes down then all connections
on this link are moved to the surviving link. Upon recovery of the failing
device or availability of a new one, the symmetric link group will be restored.

net: ethernet: fec: Prevent MII event after MII_SPEED write
The change to polled IO for MDIO completion assumes that MII events
are only generated for MDIO transactions. However on some SoCs writing
to the MII_SPEED register can also trigger an MII event. As a result,
the next MDIO read has a pending MII event, and immediately reads the
data registers before it contains useful data. When the read does
complete, another MII event is posted, which results in the next read
also going wrong, and the cycle continues.
By writing 0 to the MII_DATA register before writing to the speed
register, this MII event for the MII_SPEED is suppressed, and polled
IO works as expected.

mlxsw: Rework matchall offloading plumbing

Currently the matchall and flower are handled by registering separate
callbacks in mlxsw. That leads to faulty indication "in_hw_count 2" in
filter show command for every inserted flower filter. That happens
because matchall callback just blindly returns 0 for it and it is
wrongly accounted for as "the offloader".
I inspected different ways to fix this problem. The only clean solution
is to rework handling of matchall in mlxsw a bit. The driver newely
registers one callback for bound block which is called for both matchall
and flower filter insertions.
On the way, iron out the matchall code a bit, push it into a separate
file etc.

mlxsw: spectrum_matchall: Process matchall events from the same cb as flower
Currently there are two callbacks registered: one for matchall,
one for flower. This causes the user to see "in_hw_count 2" in TC filter
dump. Because of this and also as a preparation for future matchall
offload for rules equivalent to flower-all-match, move the processing of
shared block into matchall.c. Leave only one cb for mlxsw driver
per-block.

mlxsw: spectrum: Avoid copying sample values and use RCU pointer direcly instead
Currently, only the psample_group is accessed using RCU on RX path.
However, it is possible (unlikely) that other sample values get change
during RX processing. Fix this by having the port->sample struct
accessed as RCU pointer, containing all sample values including
psample_group pointer. That avoids extra alloc per-port, copying the
values and the race condition described above.
