Whenever we have few destinations from Flow-table type we need to put
the one that goes to the wire to be the last one.
We are using FW in order to get iterator, the FW uses RX for the first
destinations and TX for the last destination, if we want the packet to
be directed to the wire it should be done in the TX path and not in the
RX.
The code now checks if the FT is directed to the wire and if so puts it
as the last destination.

In order to have mcast offloads the driver needs the following:
It should know if that mcast comes from wire port, in addition the flow
should not be marked as any specific source, that way it will give the
flexibility for the driver not to be depended on the way iterator
implemented in the FW.

As matchall filter uses TSAR (Transmit Scheduling Arbiter) for rate
limit, the rate of police action should not be over the port's max
link speed, or the maximum aggregated speed of both ports if LAG is

When LAG is configured, functions (PF,VF,SF) can utilize the maximum
aggregated link speed for transmission. Currently the aggregated link
speed is not considered.
Hence, improve it to use the aggregated link speed by referring to the
physical port's upper bonding device when LAG is configured.

table->max_sfs is initialized in mlx5_sf_dev_table_create() and only
used to check for 0 in mlx5_sf_dev_add(). mlx5_sf_dev_add() is called
either from mlx5_sf_dev_state_change_handler() or
mlx5_sf_dev_add_active_work(). Both ensure max SF count is not 0,
using mlx5_sf_max_functions() helper before calling mlx5_sf_dev_add().
So remove the redundant check and no longer used max_sfs field.

Historically, the SF table reference counting was present in order to
protect parallel executions of devlink ops. However, since currently
this is protected with devlink instance lock, the SF table reference
counting is no longer needed. Remove it entirely.

The DesignWare IP can be synthesized with the IC_EMPTYFIFO_HOLD_MASTER_EN
parameter.
In this case, when the TX FIFO gets empty and the last command didn't have
the STOP bit (IC_DATA_CMD[9]), the controller will hold SCL low until
a new command is pushed into the TX FIFO or the transfer is aborted.
When the controller is holding SCL low, it cannot be disabled.
The transfer must first be aborted.
Also, the bus recovery won't work because SCL is held low by the master.
Check if the master is holding SCL low in __i2c_dw_disable() before trying
to disable the controller. If SCL is held low, an abort is initiated.
When the abort is done, then proceed with disabling the controller.
This whole situation can happen for instance during SMBus read data block
if the slave just responds with "byte count == 0".
This puts the driver in an unrecoverable state, because the controller is
holding SCL low and the current __i2c_dw_disable() procedure is not
working. In this situation only a SoC reset can fix the i2c bus.

therefore not mapped in the direct mapping.

c6c704cc (&dev->lock){+.+.}-{3:3}, at: phy_state_machine+0x100/0x2b8
This is because we now consistently call phy_process_state_change()
while holding phydev->lock, but the AX88772A PHY driver then goes on
to call phy_start_aneg() which tries to grab the same lock - causing
deadlock.

Currently the reset process in hns3 and firmware watchdog init process is
asynchronous. we think firmware watchdog initialization is completed
before hns3 clear the firmware interrupt source. However, firmware
initialization may not complete early.
so we add delay before hns3 clear firmware interrupt source and 5 ms delay
is enough to avoid second firmware reset interrupt.

Firmware does not respond driver commands during reset
Therefore, rule will fail to delete while the firmware is resetting
So, if failed to delete rule, set rule state to TO_DEL,
and the rule will be deleted when periodic task being scheduled.

Currently, the driver will enable unicast promisc for the function
once configure mac address fail. It's unreasonable when the failure
is caused by using same mac address with other functions. So only
enable unicast promisc when mac table full.

The device_version V3 hardware can't offload the checksum for IP in GRE
packets, but can do it for NvGRE. So default to disable the checksum and
GSO offload for GRE, but keep the ability to enable it when only using
NvGRE.

commit 133466c3bbe1 ("net: stmmac: use per-queue 64 bit statistics
where necessary") caused one regression as found by Uwe, the backtrace
looks like:
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.

The reason is the rxq|txq_stats structures are not what expected
because stmmac_open() -> __stmmac_open() the structure is overwritten
by "memcpy(&priv->dma_conf, dma_conf, sizeof(*dma_conf));"
This causes the well initialized syncp member of rxq|txq_stats is
overwritten unexpectedly as pointed out by Johannes and Uwe.
Fix this issue by moving rxq|txq_stats back to stmmac_extra_stats. For
SMP cache friendly, we also mark stmmac_txq_stats and stmmac_rxq_stats
as ____cacheline_aligned_in_smp.
