mlxsw: Bump firmware version to XX.2007.1168

Petr says:

In patch #1, bump the firmware version required by the driver to
XX.2007.1168. This version fixes several issues observed in the
offloaded datapath.

In patch #2, add support for requiring FW version on Spectrum-3 (so far
only Spectrum-1 and Spectrum-2 have had this requirement). Demand the
same version as mentioned above.

Brian Vazquez 55cced4f81 ipv6: fib6: avoid indirect calls from fib6_rule_lookup
It was reported that a considerable amount of cycles were spent on the
expensive indirect calls on fib6_rule_lookup. This patch introduces an
inline helper called pol_route_func that uses the indirect_call_wrappers
to avoid the indirect calls.

This patch saves around 50ns per call.

Performance was measured on the receiver by checking the amount of
syncookies that server was able to generate under a synflood load.

Traffic was generated using trafgen[1] which was pushing around 1Mpps on
a single queue. Receiver was using only one rx queue which help to
create a bottle neck and make the experiment rx-bounded.

These are the syncookies generated over 10s from the different runs:

====================
Multicast improvement in Ocelot and Felix drivers

This series makes some basic multicast forwarding functionality work for
Felix DSA and for Ocelot switchdev. IGMP/MLD snooping in Felix is still
missing, and there are other improvements to be made in the general area
of multicast address filtering towards the CPU, but let's get these
hardware-specific fixes out of the way first.

Vladimir Oltean 9403c158b8 net: mscc: ocelot: support IPv4, IPv6 and plain Ethernet mdb entries
The current procedure for installing a multicast address is hardcoded
for IPv4. But, in the ocelot hardware, there are 3 different procedures
for IPv4, IPv6 and for regular L2 multicast.

For IPv6 (33-33-xx-xx-xx-xx), it's the same as for IPv4
(01-00-5e-xx-xx-xx), except that the destination port mask is stuffed
into first 2 bytes of the MAC address except into first 3 bytes.

For plain Ethernet multicast, there's no port-in-address stuffing going
on, instead the DEST_IDX (pointer to PGID) is used there, just as for
unicast. So we have to use one of the nonreserved multicast PGIDs that
the hardware has allocated for this purpose.

This patch classifies the type of multicast address based on its first
bytes, then redirects to one of the 3 different hardware procedures.

Note that this gives us a really better way of redirecting PTP frames
sent at 01-1b-19-00-00-00 to the CPU. Previously, Yangbo Lu tried to add
a trapping rule for PTP EtherType but got a lot of pushback:

https://patchwork.ozlabs.org/project/netdev/patch/20190813025214.18601-5-yangbo.lu@nxp.com/

But right now, that isn't needed at all. The application stack (ptp4l)
does this for the PTP multicast addresses it's interested in (which are
configurable, and include 01-1b-19-00-00-00):

	memset(&mreq, 0, sizeof(mreq));
	mreq.mr_ifindex = index;
	mreq.mr_type = PACKET_MR_MULTICAST;
	mreq.mr_alen = MAC_LEN;
	memcpy(mreq.mr_address, addr1, MAC_LEN);

	err1 = setsockopt(fd, SOL_PACKET, PACKET_ADD_MEMBERSHIP, &mreq,
			  sizeof(mreq));

Into the kernel, this translates into a dev_mc_add on the switch network
interfaces, and our drivers know that it means they should translate it
into a host MDB address (make the CPU port be the destination).
Previously, this was broken because all mdb addresses were treated as
IPv4 (which 01-1b-19-00-00-00 obviously is not).

Vladimir Oltean 471beb11c4 net: mscc: ocelot: make the NPI port a proper target for FDB and MDB
When used in DSA mode (as seen in Felix), the DEST_IDX in the MAC table
should point to the PGID for the CPU port (PGID_CPU) and not for the
Ethernet port where the CPU queues are redirected to (also known as Node
Processor Interface - NPI).

Because for Felix this distinction shouldn't really matter (from DSA
perspective, the NPI port _is_ the CPU port), make the ocelot library
act upon the CPU port when NPI mode is enabled. This has no effect for
the mscc_ocelot driver for VSC7514, because that does not use NPI (and
ocelot->npi is -1).

Vladimir Oltean 0897ecf753 net: mscc: ocelot: fix encoding destination ports into multicast IPv4 address
The ocelot hardware designers have made some hacks to support multicast
IPv4 and IPv6 addresses. Normally, the MAC table matches on MAC
addresses and the destination ports are selected through the DEST_IDX
field of the respective MAC table entry. The DEST_IDX points to a Port
Group ID (PGID) which contains the bit mask of ports that frames should
be forwarded to. But there aren't a lot of PGIDs (only 80 or so) and
there are clearly many more IP multicast addresses than that, so it
doesn't scale to use this PGID mechanism, so something else was done.
Since the first portion of the MAC address is known, the hack they did
was to use a single PGID for _flooding_ unknown IPv4 multicast
(PGID_MCIPV4 == 62), but for known IP multicast, embed the destination
ports into the first 3 bytes of the MAC address recorded in the MAC
table.

The VSC7514 datasheet explains it like this:

    3.9.1.5 IPv4 Multicast Entries

    MAC table entries with the ENTRY_TYPE = 2 settings are interpreted
    as IPv4 multicast entries.
    IPv4 multicasts entries match IPv4 frames, which are classified to
    the specified VID, and which have DMAC = 0x01005Exxxxxx, where
    xxxxxx is the lower 24 bits of the MAC address in the entry.
    Instead of a lookup in the destination mask table (PGID), the
    destination set is programmed as part of the entry MAC address. This
    is shown in the following table.

    Table 78: IPv4 Multicast Destination Mask

        Destination Ports            Record Bit Field
        ---------------------------------------------
        Ports 10-0                   MAC[34-24]

    Example: All IPv4 multicast frames in VLAN 12 with MAC 01005E112233 are
    to be forwarded to ports 3, 8, and 9. This is done by inserting the
    following entry in the MAC table entry:
    VALID = 1
    VID = 12
    MAC = 0x000308112233
    ENTRY_TYPE = 2
    DEST_IDX = 0

But this procedure is not at all what's going on in the driver. In fact,
the code that embeds the ports into the MAC address looks like it hasn't
actually been tested. This patch applies the procedure described in the
datasheet.

Since there are many other fixes to be made around multicast forwarding
until it works properly, there is no real reason for this patch to be
backported to stable trees, or considered a real fix of something that
should have worked.

====================
mlxsw: Offload TC action pedit munge tcp/udp sport/dport

Petr says:

On Spectrum-2 and Spectrum-3, it is possible to overwrite L4 port number of
a TCP or UDP packet in the ACL engine. That corresponds to the pedit munges
of tcp and udp sport resp. dport fields. Offload these munges on the
systems where they are supported.

The current offloading code assumes that all systems support the same set
of fields. This now changes, so in patch #1 first split handling of pedit
munges by chip type. The analysis of which packet field a given munge
describes is kept generic.

Patch #2 introduces the new flexible action fields. Patch #3 then adds the
new pedit fields, and dispatches on them on Spectrum>1.

Patch #4 adds a forwarding selftest for pedit dsfield, applicable to SW as
well as HW datapaths.

Heiner Kallweit 06a14ab852 r8169: remove driver-specific mutex
Now that the critical sections are protected with RTNL lock, we don't
need a separate mutex any longer.

Heiner Kallweit abe5fc42f9 r8169: use RTNL to protect critical sections
Most relevant ops (open, close, ethtool ops) are protected with RTNL
lock by net core. Make sure that such ops can't be interrupted by
e.g. (runtime-)suspending by taking the RTNL lock in suspend ops
and the PCI error handler.

Heiner Kallweit 476c4f5de3 r8169: mark device as not present when in PCI D3
Mark the netdevice as detached whenever we go into PCI D3hot.
This allows to remove some checks e.g. from ethtool ops because
dev_ethtool() checks for netif_device_present() in the beginning.

In this context move waking up the queue out of rtl_reset_work()
because in cases where netif_device_attach() is called afterwards
the queue should be woken up by the latter function only.

Heiner Kallweit bd869245a3 net: core: try to runtime-resume detached device in __dev_open
A netdevice may be marked as detached because the parent is
runtime-suspended and not accessible whilst interface or link is down.
An example are PCI network devices that go into PCI D3hot, see e.g.
__igc_shutdown() or rtl8169_net_suspend().
If netdevice is down and marked as detached we can only open it if
we runtime-resume it before __dev_open() calls netif_device_present().

Therefore, if netdevice is detached, try to runtime-resume the parent
and only return with an error if it's still detached.

====================
prepare dwmac-meson8b for G12A specific initialization

Some users are reporting that RGMII (and sometimes also RMII) Ethernet
is not working for them on G12A/G12B/SM1 boards. Upon closer inspection
of the vendor code for these SoCs new register bits are found.

It's not clear yet how these registers work. Add a new compatible string
as the first preparation step to improve Ethernet support on these SoCs.

Martin Blumenstingl a4f63342d0 net: stmmac: dwmac-meson8b: add a compatible string for G12A SoCs
Amlogic Meson G12A, G12B and SM1 have the same (at least as far as we
know at the time of writing) PRG_ETHERNET glue register implementation.
This implementation however is slightly different from AXG as it now has
an undocument "auto cali idx val" register in PRG_ETH1[17:16] which
seems to be related to RGMII Ethernet.

Add a new compatible string for G12A SoCs so the logic for this new
register can be implemented in the future.

Sparse is complaining and giving the following warning message:
'Using plain integer as NULL pointer'.

This is not what's going on, instead {0} is used as a zero initializer
for the structure members, to indicate that the particular chip revision
does not support those particular config tables.

But since the config tables are declared globally, the unpopulated
elements are zero-initialized anyway. So, to make sparse shut up, let's
remove the zero initializers.
