This follows David Miller advice and tries to fix coalesce timer in
multi-queue scenarios.
We are now using per-queue coalesce values and per-queue TX timer.
Coalesce timer default values was changed to 1ms and the coalesce frames
to 25.
Tested in B2B setup between XGMAC2 and GMAC5.

This reverts commit 4ae0169fd1b3c792b66be58995b7e6b629919ecf.
This change in the handling of the coalesce timer is causing regression on
(at least) amlogic platforms.
Network will break down very quickly (a few seconds) after starting
a download. This can easily be reproduced using iperf3 for example.
The problem has been reported on the S805, S905, S912 and A113 SoCs
(Realtek and Micrel PHYs) and it is likely impacting all Amlogics
platforms using Gbit ethernet
No problem was seen with the platform using 10/100 only PHYs (GXL internal)
Reverting change brings things back to normal and allows to use network
again until we better understand the problem with the coalesce timer.

Currently we were running HWIF quirks before getting HW capabilities.
This is not right because some HWIF callbacks depend on HW caps.
Lets save the quirks callback and use it in a later stage.

This adds support for Flexible PPS output (which is equivalent
to per_out output of PTP subsystem).
Tested using an oscilloscope and the following commands:
1) Start PTP4L:
# ptp4l -A -4 -H -m -i eth0 &
2) Set Flexible PPS frequency:
# echo <idx> <ts> <tns> <ps> <pns> > /sys/class/ptp/ptpX/period
Where, ts/tns is start time and ps/pns is period time, and ptpX is ptp
of eth0.

Some drivers, such as DWC EQOS on Tegra, need to perform operations that
can sleep under this lock (clk_set_rate() in tegra_eqos_fix_speed()) for
proper operation. Since there is no need for this lock to be a spinlock,
convert it to a mutex instead.

This is cutting down performance. Once the timer is armed it should run
after the time expires for the first packet sent and not the last one.
After this change, running iperf, the performance gain is +/- 24%.

This adds support for U32 filter by using an HW only feature called
Flexible RX Parser. This allow us to match any given packet field with a
pattern and accept/reject or even route the packet to a specific DMA
channel.
Right now we only support acception or rejection of frame and we only
support simple rules. Though, the Parser has the flexibility of jumping to
specific rules as an if condition so complex rules can be established.
This is only supported in GMAC5.10+.
The following commands can be used to test this code:
1) Setup an ingress qdisk:
# tc qdisc add dev eth0 handle ffff: ingress
2) Setup a filter (e.g. filter by IP):
# tc filter add dev eth0 parent ffff: protocol ip u32 match ip \
src 192.168.0.3 skip_sw action drop
In every tests performed we always used the "skip_sw" flag to make sure
only the RX Parser was involved.

The Automotive Safety Pacakge (also called Safety Features) offers us
with error protection in the core by implementing ECC Protection in

In case of an uncorrectable error we call stmmac_global_err() and

The DMA engine in dwmac4 can segment a large TSO packet to several
smaller packets of (max) size Maximum Segment Size (MSS).
The DMA engine fetches and saves the MSS via a context descriptor.
This context decriptor has to be provided to each tx DMA channel.
To ensure that this is done, move struct member mss from stmmac_priv
to stmmac_tx_queue.
stmmac_reset_queues_param() now also resets mss, together with other
queue parameters, so reset of mss value can be removed from
stmmac_resume().
init_dma_tx_desc_rings() now also resets mss, together with other
queue parameters, so reset of mss value can be removed from
stmmac_open().
This fixes tx queue timeouts for dwmac4, with DT property
snps,tx-queues-to-use > 1, when running iperf3 with multiple threads.

This patch moves stmmac_clk, pclk, clk_ptp_ref and stmmac_rst to the
plat_stmmacenet_data structure. It also moves these platform variables
initialization to stmmac_platform. This was done for two reasons:
a) If PCI is used, platform related code is being executed in stmmac_main
resulting in warnings that have no sense and conceptually was not right
b) stmmac as a synopsys reference ethernet driver stack will be hosting
more and more drivers to its structure like synopsys/dwc_eth_qos.c.
These drivers have their own DT bindings that are not compatible with
stmmac's. One of the most important are the clock names, and so they need
to be parsed in the glue logic and initialized there, and that is the main
reason why the clocks were passed to the platform structure.

The driver uses a private lock for synchronization of the xmit function and
the xmit completion handler, but since the NETIF_F_LLTX flag is not set,
the xmit function is also called with the xmit_lock held.
On the other hand the completion handler uses the reverse locking order by
first taking the private lock and (in case that the tx queue had been
stopped) then the xmit_lock.
Improve the locking by removing the private lock and using only the
xmit_lock for synchronization instead.

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.
That driver has a change_mtu method explicitly for sending
a message to the hardware. If that fails it returns an
error.
Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.
However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Due to bad management of the descriptors, when use ptp4l,
kernel panics as shown below:
-----------------------------------------------------------
Unable to handle kernel NULL pointer dereference at virtual
address 000001ac
...
Internal error: Oops: 17 [#1] SMP ARM
...
Hardware name: STi SoC with Flattened Device Tree
task: c0c05e80 task.stack: c0c00000
PC is at dwmac4_wrback_get_tx_timestamp_status+0x0/0xc
LR is at stmmac_tx_clean+0x2f8/0x4d4
-----------------------------------------------------------
In case of GMAC4 the extended descriptor pointers were
used for getting the timestamp. These are NULL for this HW,
and the normal ones must be used.
The PTP also had problems on this chip due to the bad
register management and issues on the algo adopted to
setup the PTP and getting the timestamp values from the
descriptors.

breaks the procedure added by the

the entry is accessed via doing a modulo to find the "real"
position in the ring.
It is inefficient, modulo is an expensive operation.

Then, the number of elements cannot be set by command line but

This patch removes all the Koptions added to build the glue-logic files
for all different architectures: DWMAC_MESON, DWMAC_SUNXI, DWMAC_STI ...
Nowadays the stmmac needs to be compiled on several platforms; in some
case it very convenient to guarantee that its build is always completed
with success on all the branches where the driver is present.

The Ethernet controller available in Meson6 and Meson8 SoCs is a
Synopsys DesignWare MAC IP core, already supported by the stmmac
driver.
This glue layer implements some platform-specific settings needed by
the Amlogic variant.

Enabling DMA_API_DEBUG, warnings are reported at runtime
because the device driver frees DMA memory with wrong functions
and it does not call dma_mapping_error after mapping dma memory.
The first problem is fixed by of introducing a flag that helps us
keeping track which mapping technique was used, so that we can use
the right API for unmap.
This approach was inspired by the e1000 driver, which uses a similar
technique.

The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).
The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.
If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.
Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.
