The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters
as direct function arguments. This will force us to change the API (and
all drivers' functions) every time some new parameters are added.
This is part 1/2 of the fix, as suggested in [1]:
- First simplify the code by always providing a pointer to all params
(indir, key and func); the fact that some of them may be NULL seems
like a weird historic thing or a premature optimization.
It will simplify the drivers if all pointers are always present.
- Then make the functions take a dev pointer, and a pointer to a
single struct wrapping all arguments. The set_* should also take
an extack.

Commit 8fce333170 ("net: stmmac: Rework coalesce timer and fix
multi-queue races") decreased the TX coalesce timer from 40ms to 1ms.
This caused some performance regression on some target (regression was
reported at least on ipq806x) in the order of 600mbps dropping from
gigabit handling to only 200mbps.
The problem was identified in the TX timer getting armed too much time.
While this was fixed and improved in another commit, performance can be
improved even further by increasing the timer delay a bit moving from
1ms to 5ms.
The value is a good balance between battery saving by prevending too
much interrupt to be generated and permitting good performance for
internet oriented devices.

There is currently a problem with the TX timer getting armed multiple
unnecessary times causing big performance regression on some device that
suffer from heavy handling of hrtimer rearm.
The use of the TX timer is an old implementation that predates the napi
implementation and the interrupt enable/disable handling.
Due to stmmac being a very old code, the TX timer was never evaluated
again with this new implementation and was kept there causing
performance regression. The performance regression started to appear
with kernel version 4.19 with 8fce333170 ("net: stmmac: Rework coalesce
timer and fix multi-queue races") where the timer was reduced to 1ms
causing it to be armed 40 times more than before.
Decreasing the timer made the problem more present and caused the
regression in the other of 600-700mbps on some device (regression where
this was notice is ipq806x).
The problem is in the fact that handling the hrtimer on some target is
expensive and recent kernel made the timer armed much more times.
A solution that was proposed was reverting the hrtimer change and use
mod_timer but such solution would still hide the real problem in the
current implementation.
To fix the regression, apply some additional logic and skip arming the
timer when not needed.
Arm the timer ONLY if a napi is not already scheduled. Running the timer
is redundant since the same function (stmmac_tx_clean) will run in the
napi TX poll. Also try to cancel any timer if a napi is scheduled to
prevent redundant run of TX call.
With the following new logic the original performance are restored while
keeping using the hrtimer.

Even though the hardware theoretically supports up to 4 simultaneous
auxiliary snapshot capture channels, the stmmac driver does support only
a single channel to be active at a time.
Previously in case of a PTP_CLK_REQ_EXTTS request, previously active
auxiliary snapshot capture channels were silently dropped and the new
channel was activated.
Instead of silently changing the state for all consumers, log an error
and return -EBUSY if a channel is already in use in order to signal to
userspace to disable the currently active channel before enabling another one.

The STM32MP1 keeps clk_rx enabled during suspend, and therefore the
driver does not enable the clock in stm32_dwmac_init() if the device was
suspended. The problem is that this same code runs on STM32 MCUs, which
do disable clk_rx during suspend, causing the clock to never be
re-enabled on resume.
This patch adds a variant flag to indicate that clk_rx remains enabled
during suspend, and uses this to decide whether to enable the clock in
stm32_dwmac_init() if the device was suspended.
This approach fixes this specific bug with limited opportunity for
unintended side-effects, but I have a follow up patch that will refactor
the clock configuration and hopefully make it less error prone.
