This is a follow-up patch for commit 17deaf5cb3 ("net: dsa:
mv88e6xxx: create serdes_get_lane chip operation").
The .serdes_get_lane implementations access the CMODE of a port,
even though it is cached at the moment, it is safer to call them
after the mutex is locked, not before.
At the same time, check for an eventual error and return IRQ_DONE,
instead of blindly ignoring it.

The current loopback mode is to add 0x1F to the SMAC address
as the DMAC address and enable the promiscuous mode.
However, if the VF address is the same as the DMAC address,
the loopback test fails.
Loopback can be enabled in three places: SSU, MAC, and serdes.
By default, SSU loopback is enabled, so if the SMAC and the DMAC
are the same, the packets are looped back in the SSU. If SSU loopback
is disabled, packets can reach MAC even if SMAC is the same as DMAC.
Therefore, this patch disables the SSU loopback before the loopback
test. In this way, the SMAC and DMAC can be the same, and the
promiscuous mode does not need to be enabled. And this is not
valid in version 0x20.
This patch also uses a macro to replace 0x1F.

Starting with firmware version MC10.18.0, we have support for
L2 flow control. Asymmetrical configuration (Rx or Tx only) is
supported, but not pause frame autonegotioation.
Pause frame configuration is done via ethtool. By default, we start
with flow control enabled on both Rx and Tx. Changes are propagated
to hardware through firmware commands, using two flags (PAUSE,
ASYM_PAUSE) to specify Rx and Tx pause configuration, as follows:
PAUSE | ASYM_PAUSE | Rx pause | Tx pause
----------------------------------------
0 | 0 | disabled | disabled
0 | 1 | disabled | enabled
1 | 0 | enabled | enabled
1 | 1 | enabled | disabled
The hardware can automatically send pause frames when the number
of buffers in the pool goes below a predefined threshold. Due to
this, flow control is incompatible with Rx frame queue taildrop
(both mechanisms target the case when processing of ingress
frames can't keep up with the Rx rate; for large frames, the number
of buffers in the pool may never get low enough to trigger pause
frames as long as taildrop is enabled). So we set pause frame
generation and Rx FQ taildrop as mutually exclusive.

mlxsw: Various updates
Patch #1 from Amit removes 56G speed support. The reasons for this are
detailed in the commit message.
Patch #2 from Shalom ensures that the hardware does not auto negotiate
the number of used lanes. For example, if a four lane port supports 100G
over both two and four lanes, it will not advertise the two lane link
mode.
Patch #3 bumps the firmware version supported by the driver.
Patch #4 from Petr adds ethtool counters to help debug the internal PTP

====================

On Spectrum-1, timestamped PTP packets and the corresponding timestamps need to
be kept in caches until both are available, at which point they are matched up
and packets forwarded as appropriate. However, not all packets will ever see
their timestamp, and not all timestamps will ever see their packet. It is
necessary to dispose of such abandoned entries, so a garbage collector was
introduced in commit 5d23e41597 ("mlxsw: spectrum: PTP: Garbage-collect
unmatched entries").
If these GC events happen often, it is a sign of a problem. However because this
whole mechanism is taking place behind the scenes, there is no direct way to
determine whether garbage collection took place.
Therefore to fix this, on Spectrum-1 only, expose four artificial ethtool
counters for the GC events: GCd timestamps and packets, in TX and RX directions.

Commit 275e928f19 ("mlxsw: spectrum: Prevent force of 56G") prevented

This is the only speed supported by mlxsw that cannot be set when
auto-negotiation is off, which makes it difficult to write generic
tests.
Further, the speed is not supported by newer ASICs such as Spectrum-2
and to the best of our knowledge it is not used by current users.

Changes since v4:
- added Reviewed-by and Tested-by tags on first 2 patches, the others
are changed are affected by changes in patch 3/6, so I did not add
the tags, except for 5/6, which is just macro renaming
- patch 3 was changed: the serdes_get_lane returns 0 on success (lane
was discovered), -ENODEV if not lane is present on the port, and
other error if other error occured. Lane is put into a pointer of
type u8
- patches 4 and 6 were affected by this (error detecting from
serdes_get_lane)
- Andrew's complaint about the two additional parameters
(allow_over_2500 and make_cmode_writable) was addressed, by Vivien's
advice: I put a new method into chip operations structure, named
port_set_cmode_writable. This is called from mv88e6xxx_port_setup_mac
just before port_set_cmode. The method is implemented for Topaz.
The check if cmodes over 2500 should be allowed on given port is now
done in the specific port_set_cmode() that requires it, thus the
allow_over_2500 argument is not needed
Again, tested on Turris Mox with Peridot, Topaz, and Peridot + Topaz.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Currently we support SERDES on the Topaz family in a limited way: no
IRQs and the cmode is not writable, thus the mode is determined by
strapping pins.
Marvell's examples though show how to make cmode writable on port 5 and
support SGMII autonegotiation. It is done by writing hidden registers,
for which we already have code.
This patch adds support for making the cmode for the SERDES port
writable on the Topaz family, via a new chip operation,
.port_set_cmode_writable, which is called from mv88e6xxx_port_setup_mac
just before .port_set_cmode.
SERDES IRQs are also enabled for Topaz.

faster).
Look at the cmode and set SPEED_2500 if cmode is set to 2500base-x.

Simplify DSA handling of VLAN subinterface offload
Depends on Vivien Didelot's patchset:
https://patchwork.ozlabs.org/project/netdev/list/?series=127197&state=*
This patchset removes a few strange-looking guards for -EOPNOTSUPP in
dsa_slave_vlan_rx_add_vid and dsa_slave_vlan_rx_kill_vid, making that
code path no longer possible.
It also disables the code path for the sja1105 driver, which does
support editing the VLAN table, but not hardware-accelerated VLAN
sub-interfaces, therefore the check in the DSA core would be wrong.
There was no better DSA callback to do this than .port_enable, i.e.
at ndo_open time.

The switch barely supports traffic I/O, and it does that by repurposing
VLANs when there is no bridge that is taking control of them.
Letting DSA declare this netdev feature as supported (see
dsa_slave_create) would mean that VLAN sub-interfaces created on sja1105
switch ports will be hardware offloaded. That means that
net/8021q/vlan_core.c would install the VLAN into the filter tables of
the switch, potentially interfering with the tag_8021q VLANs.
We need to prevent that from happening and not let the 8021q core
offload VLANs to the switch hardware tables. In vlan_filtering=0 modes
of operation, the switch ports can pass through VLAN-tagged frames with
no problem.
