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).

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).

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.

Certain ACL actions are only available on some Spectrum revisions. In

new ops struct intended to hold these differences, mlxsw_sp_rulei_ops.
Prime it with a sole member, act_mangle_field, meant for handling of
pedit mangles.

Create two ops structures, one for Spectrum-1, the other for Spectrum-2
and above. Add callbacks for act_mangle_field and dispatch to the common
handler.

Invoke mlxsw_sp_rulei_ops.act_mangle_field from the field mangler
instead of calling the common handler directly.

9c90eea310 net: mscc: ocelot: move net_device related functions to ocelot_net.c
The ocelot hardware library shouldn't contain too much net_device
specific code, since it is shared with DSA which abstracts that
structure away. So much as much of this code as possible into the
mscc_ocelot driver and outside of the common library.

We're making an exception for MDB and LAG code. That is not yet exported
to DSA, but when it will, most of the code that's already in ocelot.c
will remain there. So, there's no point in moving code to ocelot_net.c
just to move it back later.

We could have moved all net_device code to ocelot_vsc7514.c directly,
but let's operate under the assumption that if a new switchdev ocelot
driver gets added, it'll define its SoC-specific stuff in a new
ocelot_vsc*.c file and it'll reuse the rest of the code.

d9feb90499 net: mscc: ocelot: move ocelot_regs.c into ocelot_vsc7514.c
ocelot_regs.c actually shouldn't be part of the common library. It
describes the register map of the VSC7514 switch. The way ocelot
switches work, they'll have highly optimized register maps, so another
SoC will likely have the same registers but laid out completely
different in memory (so there's little room for reusing this structure).
So move it to ocelot_vsc7514.c instead.

14addfb635 net: mscc: ocelot: rename MSCC_OCELOT_SWITCH_OCELOT to MSCC_OCELOT_SWITCH
Putting 'ocelot' in the config's name twice just to say that 'it's the
ocelot driver running on the ocelot SoC' is a bit confusing. Instead,
it's just the ocelot driver. Now that we've renamed the previous symbol
that was holding the MSCC_OCELOT_SWITCH_OCELOT into *_LIB (because
that's what it is), we're free to use this name for the driver.

f4d0323bae net: mscc: ocelot: convert MSCC_OCELOT_SWITCH into a library
Hide the CONFIG_MSCC_OCELOT_SWITCH option from users. It is meant to be
only a hardware library which is selected by the drivers that use it
(ocelot, felix).

Since it is "selected" from Kconfig, all its dependencies are manually
transferred to the driver that selects it. This is because "select" in
Kconfig language is a bit of a mess, and doesn't handle dependencies of
selected options quite right.

56583862b8 net: mscc: ocelot: rename module to mscc_ocelot
mscc_ocelot is a slightly better name for a module than ocelot_board or
ocelot_vsc7514 is, so let's use that.

7eb5c96a7c net: mscc: ocelot: use plain int when interacting with TCAM tables
sparse is rightfully complaining about the fact that:

warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
   26 |   __builtin_constant_p((l) > (h)), (l) > (h), 0)))
      |                            ^

   39 |  (GENMASK_INPUT_CHECK(h, l) + __GENMASK(h, l))
      |   ^~~~~~~~~~~~~~~~~~~
note: in expansion of macro ‘GENMASK’
  127 |   mask = GENMASK(width, 0);
      |          ^~~~~~~

So replace the variables that go into GENMASK with plain, signed integer
types.
