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).

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
particular, L4_PORT_ACTION is not available on Spectrum-1. Introduce a
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.

The second commit cited below performed a cast of 'u32 buffsize' to
'(u16 *)' when calling mlxsw_sp_port_headroom_8x_adjust():
mlxsw_sp_port_headroom_8x_adjust(mlxsw_sp_port, (u16 *) &buffsize);
Colin noted that this will behave differently on big endian
architectures compared to little endian architectures.
Fix this by following Colin's suggestion and have the function accept
and return 'u32' instead of passing the current size by reference.

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.

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.

Let's rename the structures and functions to something more generic, so
that VCAP IS1 structures (which would otherwise have to be called

Some renaming that was done:

struct ocelot_acl_block -> struct ocelot_vcap_block
enum ocelot_ace_type -> enum ocelot_vcap_key_type
struct ocelot_ace_vlan -> struct ocelot_vcap_key_vlan

struct ocelot_ace_stats -> struct ocelot_vcap_stats
enum ocelot_ace_type -> enum ocelot_vcap_key_type

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.

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.

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

early validation days of this feature). And the code was
