Move from simple ida to xarray for storing and loading the ptp_clock
pointer. This prepares support for future hardware timestamp selection by
being able to link the ptp clock index to its pointer.

Commit 3e2f544dd8a33 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.
Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of in this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Remove the allocation in the vxlan driver and leverage the network
core allocation instead.

When creating a helper to allocate and align an skb one location where
the skb data size was updated was missed. This can lead to a warning
being printed when the memory is being unmapped as it now always unmap
the maximum frame size, instead of the size after it have been
aligned.
This was correctly done for RZ/G2L but missed for R-Car.

The family struct is auto-generated for new families, support
use of the sock_priv_* mechanism added in commit a731132424ad
("genetlink: introduce per-sock family private storage").
For example if the family wants to use struct sk_buff as its
private struct (unrealistic but just for illustration), it would
add to its spec:
kernel-family:
headers: [ "linux/skbuff.h" ]
sock-priv: struct sk_buff
ynl-gen-c will declare the appropriate priv size and hook
in function prototypes to be implemented by the family.

Matthieu Baerts says:
====================
selftests: mptcp: various improvements
In this series from Geliang, there are various improvements in MPTCP
selftests: sharing code, doing actions the same way, colours, etc.
Patch 1 prints all error messages to stdout: what was done in almost all
other MPTCP selftests. This can be now easily changed later if needed.
Patch 2 makes sure the test counter is continuous in mptcp_connect.sh.
Patch 3 aligns the messages that are printed in mptcp_connect.sh.
Patch 4 prints each test results in mptcp_sockopt.sh, similar to what we
have in the TAP output.
Patch 5 moves the different test counters to a single one in
mptcp_lib.sh, to uniform how it is used.
Patch 6 moves how titles are printed from mptcp_join.sh to the lib, to
be reused in patch 7 by all other MPTCP selftests.
Patch 8 uses the '+=' operator to append strings instead of repeating
twice the variable name: that's shorter, easier to read.
Patch 9 adds colours for the [ OK ], [SKIP], [FAIL] and INFO keywords in
all MPTCP selftests.
Patch 10 to 12 are some preparation patches for patch 13: patch 10
modifies how some 'test_fail' helpers, patch 11 moves a helper from
userspace_pm.sh to the lib, and patch 12 changes where titles are
printed in userspace_pm.sh. Patch 13 moves some duplicated helpers from
mptcp_join.sh and userspace_pm.sh to mptcp_lib.sh.
Patch 14 moves duplicated read-only variables from mptcp_join.sh and
userspace_pm.sh to mptcp_lib.sh as well.
Patch 15 uses explicit variables instead of hard-coded numbers for the
exit status.

are arguments (if [ ${#} -gt 0 ]) in userspace_pm.sh, add arguments
"unexpected type: ${type}" when calling test_fail() from test_remove().
Then mptcp_lib_pr_fail() can be used in check_expected_one() instead of

To unify the output formats of all test scripts, this patch adds
four more helpers:
mptcp_lib_pr_ok()
mptcp_lib_pr_skip()
mptcp_lib_pr_fail()
mptcp_lib_pr_info()
to print out [ OK ], [SKIP], [FAIL] and 'INFO: ' with colors. Use them
in all scripts to print the "ok/skip/fail/info' using the same 'format'.
Having colors helps to quickly identify issues when looking at a long
list of output logs and results.
Note that now all print the same keywords, which was not the case
before, but it is good to uniform that.

This patch uses addition assignment operator (+=) to append strings
instead of duplicating the variable name in mptcp_connect.sh and
mptcp_join.sh.
This can make the statements shorter.
Note: in mptcp_connect.sh, add a local variable extra in do_transfer to
save the various extra warning logs, using += to append it. And add a
new variable tc_info to save various tc info, also using += to append it.
This can make the code more readable and prepare for the next commit.

This patch adds a new variable MPTCP_LIB_TEST_FORMAT as the test title
printing format. Also add a helper mptcp_lib_print_title() to use this
format to print the test title with test counters. They are used in
mptcp_join.sh first.
Each MPTCP selftest is having subtests, and it helps to give them a
number to quickly identify them. This can be managed by mptcp_lib.sh,
reusing what has been done here. The following commit will use these
new helpers in the other tests.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

====================
mlxsw: Support for nexthop group statistics
ECMP is a fundamental component in L3 designs. However, it's fragile. Many
factors influence whether an ECMP group will operate as intended: hash
policy (i.e. the set of fields that contribute to ECMP hash calculation),
neighbor validity, hash seed (which might lead to polarization) or the type
of ECMP group used (hash-threshold or resilient).
At the same time, collection of statistics that would help an operator
determine that the group performs as desired, is difficult.
Support for nexthop group statistics and their HW collection has been
introduced recently. In this patch set, add HW stats collection support
to mlxsw.
This patchset progresses as follows:
- Patches #1 and #2 add nexthop IDs to notifiers.
- Patches #3 and #4 are code-shaping.
- Patches #5, #6 and #7 adjust the flow counter code.
- Patches #8 and #9 add HW nexthop counters.
- Patch #10 adjusts the HW counter code to allow sharing the same counter
for several resilient group buckets with the same NH ID.
- Patch #11 adds a selftest.

Add to lib.sh support for fetching NH stats, and a new library,
router_mpath_nh_lib.sh, with the common code for testing NH stats.
Use the latter from router_mpath_nh.sh and router_mpath_nh_res.sh.
The test works by sending traffic through a NH group, and checking that the
reported values correspond to what the link that ultimately receives the
traffic reports having seen.

For resilient groups, we can reuse the same counter for all the buckets
that share the same nexthop. Keep a reference count per counter, and keep
all these counters in a per-next hop group xarray, which serves as a
NHID->counter cache. If a counter is already present for a given NHID, just
take a reference and use the same counter.

When hw_stats is set on a group, install nexthop counters on members of a
group.
Counter allocation request is moved from nexthop object initialization to
the update code. The previous placement made sense: when the counters are
enabled by dpipe, the counters are installed to all existing nexthops and
all nexthops created from then on get them. For the finer-grained nexthop
group statistics, this is unsuitable. The existing placement was kept for
the IPv4 and IPv6 nexthops.
Resilient group replacement emits a pre_replace notification, and then any
bucket_replace notifications if there were any replacements at all. If the
group is balanced and the nexthop composition of the replaced group didn't
change, there will be no such notifiers. Therefore hook to the pre_replace
notifier and mark all buckets for update, to un/install the counters.
When reporting deltas for resilient groups, use the nexthop ID that we
stored in a previous patch to look up to which nexthop a bucket
contributes.

The core interfaces for collecting per-NH statistics are built around
nexthops even for resilient groups. Because mlxsw models each bucket as a
nexthop, the core next hop that a given bucket contributes to needs to be
looked up. In order to be able to match the two up, we need to track
nexthop ID for members of group nexthop objects. For simplicity, do it for
all nexthop objects, not just group members.

The next patch will add the ability to share nexthop counters among
mlxsw nexthops backed by the same core nexthop. To have a place to store
reference count, the counter should be kept in a dedicated structure. In
this patch, introduce the structure together with the related helpers, sans
the refcount, which comes in the next patch.

The NEXTHOP_EVENT_RES_TABLE_PRE_REPLACE notifier currently keeps the group
ID unset. That makes it impossible to look up the group for which the
notifier is intended. This is not an issue at the moment, because the only
client is netdevsim, and that just so that it veto replacements, which is a
static property not tied to a particular group. But for any practical use,
the ID is necessary. Set it.

Disable LEDs just before resetting the MT7530 to avoid
situations where the ESW_P4_LED_0 and ESW_P3_LED_0 pin
states may cause an unintended external crystal frequency
to be selected.
The HT_XTAL_FSEL (External Crystal Frequency Selection)
field of HWTRAP (the Hardware Trap register) stores a
2-bit value that represents the state of the ESW_P4_LED_0
and ESW_P4_LED_0 pins (seemingly) sampled just after the
MT7530 has been reset, as:
ESW_P4_LED_0 ESW_P3_LED_0 Frequency
-----------------------------------------
0 1 20MHz
1 0 40MHz
1 1 25MHz
The value of HT_XTAL_FSEL is bootstrapped by pulling
ESW_P4_LED_0 and ESW_P3_LED_0 up or down accordingly,
but:
if a 40MHz crystal has been selected and
the ESW_P3_LED_0 pin is high during reset,
or a 20MHz crystal has been selected and
the ESW_P4_LED_0 pin is high during reset,
then the value of HT_XTAL_FSEL will indicate
that a 25MHz crystal is present.
By default, the state of the LED pins is PHY controlled
to reflect the link state.
To illustrate, if a board has:
5 ports with active low LED control,
and HT_XTAL_FSEL bootstrapped for 40MHz.
When the MT7530 is powered up without any external
connection, only the LED associated with Port 3 is
illuminated as ESW_P3_LED_0 is low.
In this state, directly after mt7530_setup()'s reset
is performed, the HWTRAP register (0x7800) reflects
the intended HT_XTAL_FSEL (HWTRAP bits 10:9) of 40MHz:
mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007dcf
>>> bin(0x7dcf >> 9 & 0b11)
'0b10'
But if a cable is connected to Port 3 and the link
is active before mt7530_setup()'s reset takes place,
then HT_XTAL_FSEL seems to be set for 25MHz:
mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007fcf
>>> bin(0x7fcf >> 9 & 0b11)
'0b11'
Once HT_XTAL_FSEL reflects 25MHz, none of the ports
are functional until the MT7621 (or MT7530 itself)
is reset.
By disabling the LED pins just before reset, the chance
of an unintended HT_XTAL_FSEL value is reduced.
