TSN stream (802.1Qci, 802.1CB) filters are also accessed through
STAT_VIEW, just like the port registers, but these counters are per
stream, rather than per port. So we don't keep them in
ocelot_port_update_stats().
What we can do, however, is we can create register definitions for them
just like we have for the port counters, and delete the last remaining
user of the SYS_CNT register + a group index (read_gix).

To support SPI-controlled switches in the future, access to
SYS_STAT_CFG_STAT_VIEW needs to be done outside of any spinlock
protected region, but it still needs to be serialized (by a mutex).
Split the ocelot->stats_lock spinlock into a mutex that serializes
indirect access to hardware registers (ocelot->stat_view_lock) and a
spinlock that serializes access to the u64 ocelot->stats array.

The Felix PSFP counters suffer from the same problem as the ocelot
ndo_get_stats64 ones - they are 32-bit, so they can easily overflow and
this can easily go undetected.
Add a custom hook in ocelot_check_stats_work() through which driver
specific actions can be taken, and update the stats for the existing
PSFP filters from that hook.
Previously, vsc9959_psfp_filter_add() and vsc9959_psfp_filter_del() were
serialized with respect to each other via rtnl_lock(). However, with the
new entry point into &psfp->sfi_list coming from the periodic worker, we
now need an explicit mutex to serialize access to these lists.
We used to keep a struct felix_stream_filter_counters on stack, through
which vsc9959_psfp_stats_get() - a FLOW_CLS_STATS callback - would
retrieve data from vsc9959_psfp_counters_get(). We need to become
smarter about that in 3 ways:
- we need to keep a persistent set of counters for each stream instead
of keeping them on stack
- we need to promote those counters from u32 to u64, and create a
procedure that properly keeps 64-bit counters. Since we clear the
hardware counters anyway, and we poll every 2 seconds, a simple
increment of a u64 counter with a u32 value will perfectly do the job.
- FLOW_CLS_STATS also expect incremental counters, so we also need to
zeroize our u64 counters every time sch_flower calls us

if_link.h says:
* @rx_dropped: Number of packets received but not processed,
* e.g. due to lack of resources or unsupported protocol.
* For hardware interfaces this counter may include packets discarded
* due to L2 address filtering but should not include packets dropped
* by the device due to buffer exhaustion which are counted separately in
* @rx_missed_errors (since procfs folds those two counters together).
Currently we report "stats->rx_dropped = dev->stats.rx_dropped", the
latter being incremented by various entities in the stack. This is not
wrong, but we'd like to move ocelot_get_stats64() in the common ocelot
switch lib which is independent of struct net_device.
To do that, report the hardware RX drop counters instead. These drops
are due to policer action, or due to no destinations. When we have no
memory in the queue system, report this through rx_missed_errors, as
instructed.

The main C file of the ocelot switch lib, ocelot.c, is getting larger
and larger, and there are plans to add more logic related to stats.
So it seems like an appropriate moment to split the statistics code to a
new file.

We want to introduce elements kept in ocelot->stats that aren't exposed
to the unstructured ethtool -S (so they won't have their name populated),
but are otherwise checked for 32-bit wraparounds by
ocelot_port_update_stats().
This isn't possible today because ocelot_prepare_stats_regions() skips
over ocelot_stat_layout elements with no name. Now that we've changed
struct ocelot_stat_layout to keep the absolute register address rather
than the offset relative to SYS_CNT, we can make use of the unpopulated
"reg" value of 0 to mean that the counter isn't present on the current
switch revision, and skip it from the preparation of bulk regions.

DSA is integrated with the new standardized ethtool -S --groups option,
but the felix driver only exports unstructured statistics.
Reuse the array of 64-bit statistics collected by ocelot_check_stats_work(),
but just export select values from it.
Since ocelot_check_stats_work() runs periodically to avoid 32-bit
overflow, and the ethtool calling context is sleepable, we update the
64-bit stats one more time, to provide up-to-date values. The locking
scheme with a mutex followed by a spinlock is a bit hard to digest, so
we create and use a ocelot_port_stats_run() helper with a callback that
populates the ethool stats group the caller is interested in.
The exported stats are:
ethtool -S swp0 --groups eth-phy
ethtool -S swp0 --groups eth-mac
ethtool -S swp0 --groups eth-ctrl
ethtool -S swp0 --groups rmon
ethtool --include-statistics --show-pause swp0

The hardware counter is called C_TX_AGED, so rename SYS_COUNT_TX_AGING
to SYS_COUNT_TX_AGED. This will become important since we want to
minimize the way in which we declare struct ocelot_stat_layout elements,
using the C preprocessor.

The current definition of struct ocelot_stat_layout is long-winded (4
lines per entry, and we have hundreds of entries), so we could make an
effort to use the C preprocessor and reduce the line count.
Create an implicit correspondence between enum ocelot_reg, which tells
us the register address (SYS_COUNT_RX_OCTETS etc) and enum ocelot_stat
which allows us to index the ocelot->stats array (OCELOT_STAT_RX_OCTETS
etc), and don't require us to specify both when we define what stats
each switch family has.
Create an OCELOT_STAT() macro that pairs only an enum ocelot_stat to an
enum ocelot_reg, and an OCELOT_STAT_ETHTOOL() macro which also contains
a name exported to the unstructured ethtool -S stringset API. For now,
we define all counters as having the OCELOT_STAT_ETHTOOL() kind, but we
will add more counters in the future which are not exported to the
unstructured ethtool -S.

All switch families supported by the ocelot lib (ocelot, felix, seville)
export the same registers so far. But for example felix also has TSN
counters, while the others don't.
To reduce the bloat even further, create an OCELOT_COMMON_STATS() macro
which just lists all stats that are common between switches. The array
elements are still replicated among all of vsc9959_stats_layout,
vsc9953_stats_layout and ocelot_stats_layout.
