Prevent options not supported by the PHY from being requested to it by the MAC
Whenever a WOL option is supported by both, the PHY is given priority
since that usually leads to better power savings.

When Wake-on-LAN (WoL) is active and the system is in suspend mode, triggering
a system event can wake the system from sleep, which may block the data path.
To restore normal data path functionality after waking, disable all wake-up
events. Furthermore, clear all Write 1 to Clear (W1C) status bits by writing
1's to them.

Lan966x is adding ptp traps to redirect the ptp frames to the CPU such
that the HW will not forward these frames anywhere. The issue is that in
case ptp is not enabled and the timestamping source is et to
HWTSTAMP_SOURCE_NETDEV then these traps would not be removed on the
error path.
Fix this by removing the traps in this case as they are not needed.

A debugfs directory entry is create early during probe(). This entry is
not removed on error path leading to some "already present" issues in
case of EPROBE_DEFER.
Create this entry later in the probe() code to avoid the need to change
many 'return' in 'goto' and add the removal in the already present error
path.

Simon reported that ndo_change_mtu() methods were never
updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted
in commit 501a90c94510 ("inet: protect against too small
mtu values.")
We read dev->mtu without holding RTNL in many places,
with READ_ONCE() annotations.
It is time to take care of ndo_change_mtu() methods
to use corresponding WRITE_ONCE()

The PTP_CMD_CTL is a self clearing register which controls the PTP clock
values. In the current implementation driver waits for a duration of 20
sec in case of HW failure to clear the PTP_CMD_CTL register bit. This
timeout of 20 sec is very long to recognize a HW failure, as it is
typically cleared in one clock(<16ns). Hence reducing the timeout to 1 sec
would be sufficient to conclude if there is any HW failure observed. The
usleep_range will sleep somewhere between 1 msec to 20 msec for each
iteration. By setting the PTP_CMD_CTL_TIMEOUT_CNT to 50 the max timeout
is extended to 1 sec.

The fragment lookup should only be performed, when
at least one of the fragment flags are set.
This change was deliberately not included in commit
68aba00483c7 ("net: sparx5: flower: fix fragment flags handling")
as it's only needed for future proffing the code, since
"mask" is currently only set in conjunction with the
fragment flags.
(The 3rd flag FLOW_DIS_ENCAPSULATION is only used with "key")

The hardware supports three independent mirroring probes. Each probe can
be configured to mirror rx or tx traffic (direction).
Using tc matchall, it is now possible to add a source port and a monitor
port to a mirror probe. Depending on the mirror direction, rx or tx
traffic from a source port will be mirrored to the monitor port.
A single source port can be a member of multiple mirror probes.

I noticed that only 3 out of the 4 input bits were used,
mt.key->flags & FLOW_DIS_IS_FRAGMENT was never checked.
In order to avoid a complicated maze, I converted it to
use a 16 byte mapping table.
As shown in the table below the old heuristics doesn't
always do the right thing, ie. when FLOW_DIS_IS_FRAGMENT=1/1
then it used to only match follow-up fragment packets.
Here are all the combinations, and their resulting new/old
VCAP key/mask filter:
/- FLOW_DIS_IS_FRAGMENT (key/mask)
| /- FLOW_DIS_FIRST_FRAG (key/mask)
| | /-- new VCAP fragment (key/mask)
v v v v- old VCAP fragment (key/mask)
0/0 0/0 -/- -/- impossible (due to entry cond. on mask)
0/0 0/1 -/- 0/3 !! invalid (can't match non-fragment + follow-up frag)
0/0 1/0 -/- -/- impossible (key > mask)
0/0 1/1 1/3 1/3 first fragment
0/1 0/0 0/3 3/3 !! not fragmented
0/1 0/1 0/3 3/3 !! not fragmented (+ not first fragment)
0/1 1/0 -/- -/- impossible (key > mask)
0/1 1/1 -/- 1/3 !! invalid (non-fragment and first frag)
1/0 0/0 -/- -/- impossible (key > mask)
1/0 0/1 -/- -/- impossible (key > mask)
1/0 1/0 -/- -/- impossible (key > mask)
1/0 1/1 -/- -/- impossible (key > mask)
1/1 0/0 1/1 3/3 !! some fragment
1/1 0/1 3/3 3/3 follow-up fragment
1/1 1/0 -/- -/- impossible (key > mask)
1/1 1/1 1/3 1/3 first fragment
In the datasheet the VCAP fragment values are documented as:
0 = no fragment
1 = initial fragment
2 = suspicious fragment
3 = valid follow-up fragment
Result: 3 combinations match the old behavior,
3 combinations have been corrected,
2 combinations are now invalid, and fail,
8 combinations are impossible.
It should now be aligned with how FLOW_DIS_IS_FRAGMENT
and FLOW_DIS_FIRST_FRAG is set in __skb_flow_dissect() in
net/core/flow_dissector.c
Since the VCAP fragment values are not a bitfield, we have
to ignore the suspicious fragment value, eg. when matching
on any kind of fragment with FLOW_DIS_IS_FRAGMENT=1/1.
Only compile tested, and logic tested in userspace, as I
unfortunately don't have access to this switch chip (yet).

The enabling/disabling of EEE in the MAC should happen as a result of
auto negotiation. So move the enable/disable into
lan743x_phy_link_status_change() which gets called by phylib when
there is a change in link status.
lan743x_ethtool_set_eee() now just programs the hardware with the LTI
timer value, and passed everything else to phylib, so it can correctly
setup the PHY.
lan743x_ethtool_get_eee() relies on phylib doing most of the work, the
MAC driver just adds the LTI timer value.

Both registers used when doing manual injection or fdma injection are
shared between all the net devices of the switch. It was noticed that
when having two process which each of them trying to inject frames on
different ethernet ports, that the HW started to behave strange, by
sending out more frames then expected. When doing fdma injection it is
required to set the frame in the DCB and then make sure that the next
pointer of the last DCB is invalid. But because there is no locks for
this, then easily this pointer between the DCB can be broken and then it
would create a loop of DCBs. And that means that the HW will
continuously transmit these frames in a loop. Until the SW will break
this loop.
Therefore to fix this issue, add a spin lock for when accessing the
registers for manual or fdma injection.

There is a crash when adding one of the lan966x interfaces under a lag
interface. The issue can be reproduced like this:
ip link add name bond0 type bond miimon 100 mode balance-xor
ip link set dev eth0 master bond0
The reason is because when adding a interface under the lag it would go
through all the ports and try to figure out which other ports are under
that lag interface. And the issue is that lan966x can have ports that are
NULL pointer as they are not probed. So then iterating over these ports
it would just crash as they are NULL pointers.
The fix consists in actually checking for NULL pointers before accessing
something from the ports. Like we do in other places.

lan743x_ptp_request_tx_timestamp uses spin_lock_bh, but it is
only called from lan743x_tx_xmit_frame where all IRQs are
already disabled.
This fixes the "IRQs not enabled as expected" warning.

On lan966x, it is possible to use debugfs to print different information
about the VCAPs. Information like, if it is enabled, how the ports are
configured, print the actual rules. The issue is that when printing how
the ports are configured for IS1 lookups, it was parsing the wrong
register to get this information. The fix consists in reading the
correct register that contains this information.

In order to pass EEE link modes beyond bit 32 to userspace we have to
complement the 32 bit bitmaps in struct ethtool_eee with linkmode
bitmaps. Therefore, similar to ethtool_link_settings and
ethtool_link_ksettings, add a struct ethtool_keee. In a first step
it's an identical copy of ethtool_eee. This patch simply does a
s/ethtool_eee/ethtool_keee/g for all users.
No functional change intended.

In case the interface between the MAC and the PHY is SGMII, then the bit
GIGA_MODE on the MAC side needs to be set regardless of the speed at
which it is running.

eee_active is set by phy_ethtool_get_eee() already, using the same
logic plus an additional check against link speed/duplex values.
See genphy_c45_eee_is_active() for details.
So we can remove this line.

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.

This patch converts some basic cases of ethtool_sprintf() to
ethtool_puts().
The conversions are used in cases where ethtool_sprintf() was being used
with just two arguments:
| ethtool_sprintf(&data, buffer[i].name);
or when it's used with format string: "%s"
| ethtool_sprintf(&data, "%s", buffer[i].name);
which both now become:
| ethtool_puts(&data, buffer[i].name);

The LAN743x/PCI11xxx DMA descriptors are always 4 dwords long, but the
device supports placing the descriptors in memory back to back or
reserving space in between them using its DMA_DESCRIPTOR_SPACE (DSPACE)
configurable hardware setting. Currently DSPACE is unnecessarily set to
match the host's L1 cache line size, resulting in space reserved in
between descriptors in most platforms and causing a suboptimal behavior
(single PCIe Mem transaction per descriptor). By changing the setting
to DSPACE=16 many descriptors can be packed in a single PCIe Mem
transaction resulting in a massive performance improvement in
bidirectional tests without any negative effects.
Tested and verified improvements on x64 PC and several ARM platforms
(typical data below)
