As we now have the plat_dat->init()/plat_dat->exit() populated which
have the required functionality on suspend/resume, we can now use
stmmac_pltfr_pm_ops which has methods that call these two functions.
Switch over to use this.
Doing so also fills in the runtime PM ops and _noirq variants as well.

Using stmmac_pltfr_probe() simplifies the probe function. This will not
only call plat_dat->init (sun8i_dwmac_init), but also plat_dat->exit
(sun8i_dwmac_exit) appropriately if stmmac_dvr_probe() fails. This
results in an overall simplification of the glue driver.

Phylink will already limit the MAC speed according to the interface,
so if 2500BASE-X is selected, the maximum speed will be 2.5G.
Similarly, if SGMII is selected, the maximum speed will be 1G.
It is, therefore, not necessary to set a speed limit. Remove setting
plat_dat->max_speed from this glue driver.

Currently, bnxt_en driver satisfies the requirements of the Device
memory TCP, which is HDS.
So, it implements rx-side Device memory TCP for bnxt_en driver.
It requires only converting the page API to netmem API.
`struct page` of agg rings are changed to `netmem_ref netmem` and
corresponding functions are changed to a variant of netmem API.
It also passes PP_FLAG_ALLOW_UNREADABLE_NETMEM flag to a parameter of
page_pool.
The netmem will be activated only when a user requests devmem TCP.
When netmem is activated, received data is unreadable and netmem is
disabled, received data is readable.
But drivers don't need to handle both cases because netmem core API will
handle it properly.
So, using proper netmem API is enough for drivers.
Device memory TCP can be tested with
tools/testing/selftests/drivers/net/hw/ncdevmem.
This is tested with BCM57504-N425G and firmware version 232.0.155.8/pkg
232.1.132.8.

The driver allocates ring elements using GFP_DMA flags. There is
no dependency from LAN743x hardware on memory allocation should be
in DMA_ZONE. Hence modifying the flags to use only GFP_ATOMIC. This
is consistent with other callers of lan743x_rx_init_ring_element().

of_get_mac_address() might fetch the MAC address from NVMEM and that
driver might not have been loaded. In that case, -EPROBE_DEFER is
returned. Right now, this will trigger an immediate fallback to
am65_cpsw_am654_get_efuse_macid() possibly resulting in a random MAC
address although the MAC address is stored in the referenced NVMEM.
Fix it by handling the -EPROBE_DEFER return code correctly. This also
means that the creation of the MDIO device has to be moved to a later
stage as -EPROBE_DEFER must not be returned after child devices are
created.

The PTP_PEROUT_REQUEST2 ioctl has gained support for flags specifying
specific output behavior including PTP_PEROUT_ONE_SHOT,
PTP_PEROUT_DUTY_CYCLE, PTP_PEROUT_PHASE.
Driver authors are notorious for not checking the flags of the request.
This results in misinterpreting the request, generating an output signal
that does not match the requested value. It is anticipated that even more
flags will be added in the future, resulting in even more broken requests.
Expecting these issues to be caught during review or playing whack-a-mole
after the fact is not a great solution.
Instead, introduce the supported_perout_flags field in the ptp_clock_info
structure. Update the core character device logic to explicitly reject any
request which has a flag not on this list.
This ensures that drivers must 'opt in' to the flags they support. Drivers
which don't set the .supported_perout_flags field will not need to check
that unsupported flags aren't passed, as the core takes care of this.
Update the drivers which do support flags to set this new field.
Note the following driver files set n_per_out to a non-zero value but did
not check the flags at all:
• drivers/ptp/ptp_clockmatrix.c
• drivers/ptp/ptp_idt82p33.c
• drivers/ptp/ptp_fc3.c

The PTP_EXTTS_REQUEST(2) ioctl has a flags field which specifies how the
external timestamp request should behave. This includes which edge of the
signal to timestamp, as well as a specialized "offset" mode. It is expected
that more flags will be added in the future.
Driver authors routinely do not check the flags, often accepting requests
with flags which they do not support. Even drivers which do check flags may
not be future-proofed to reject flags not yet defined. Thus, any future
flag additions often require manually updating drivers to reject these
flags.
This approach of hoping we catch flag checks during review, or playing
whack-a-mole after the fact is the wrong approach.
Introduce the "supported_extts_flags" field to the ptp_clock_info
structure. This field defines the set of flags the device actually
supports.
Update the core character device logic to check this field and reject
unsupported requests. Getting this right is somewhat tricky. First, to
avoid unnecessary repetition and make basic functionality work when
.supported_extts_flags is 0, the core always accepts the PTP_ENABLE_FEATURE
flag. This flag is used to set the 'on' parameter to the .enable function
and is thus always 'supported' by all drivers.
For backwards compatibility, the PTP_RISING_EDGE and PTP_FALLING_EDGE flags
are merely "hints" when using the old PTP_EXTTS_REQUEST ioctl, and are not
expected to be enforced. If the user issues PTP_EXTTS_REQUEST2, the
PTP_STRICT_FLAGS flag is added which is supposed to inform the driver to
strictly validate the flags and reject unsupported requests. To handle
this, first check if the driver reports PTP_STRICT_FLAGS support. If it
does not, then always allow the PTP_RISING_EDGE and PTP_FALLING_EDGE flags.
This keeps backwards compatibility with the original PTP_EXTTS_REQUEST
ioctl where these flags are not guaranteed to be honored.
This way, drivers which do not set the supported_extts_flags will continue
to accept requests for the original PTP_EXTTS_REQUEST ioctl. The core will
automatically reject requests with new flags, and correctly reject requests
with PTP_STRICT_FLAGS, where the driver is supposed to strictly validate
the flags.
Update the various drivers, refactoring their validation logic into the
.supported_extts_flags field. For consistency and readability,
PTP_ENABLE_FEATURE is not set in the supported flags list, and
PTP_EXTTS_EDGES is expanded to PTP_RISING_EDGE | PTP_FALLING_EDGE in all
cases.
Note the following driver files set n_ext_ts to a non-zero value but did
not check flags at all:
• drivers/net/ethernet/freescale/dpaa2/dpaa2-ptp.c
• drivers/net/ethernet/freescale/enetc/enetc_ptp.c
• drivers/net/ethernet/intel/i40e/i40e_ptp.c
• drivers/net/ethernet/marvell/octeontx2/nic/otx2_ptp.c
• drivers/net/ethernet/renesas/ravb_ptp.c
• drivers/net/ethernet/renesas/rtsn.c
• drivers/net/ethernet/renesas/rtsn.h
• drivers/net/ethernet/ti/am65-cpts.c
• drivers/net/ethernet/ti/cpts.h
• drivers/net/ethernet/ti/icssg/icss_iep.c
• drivers/net/ethernet/xscale/ptp_ixp46x.c
• drivers/net/phy/bcm-phy-ptp.c
• drivers/ptp/ptp_ocp.c
• drivers/ptp/ptp_pch.c
• drivers/ptp/ptp_qoriq.c
These drivers behavior does change slightly: they will now reject the
PTP_EXTTS_REQUEST2 ioctl, because they do not strictly validate their
flags. This also makes them no longer incorrectly accept PTP_EXT_OFFSET.
Also note that the renesas ravb driver does not support PTP_STRICT_FLAGS.
We could leave the .supported_extts_flags as 0, but I added the
PTP_RISING_EDGE | PTP_FALLING_EDGE since the driver previously manually
validated these flags. This is equivalent to 0 because the core will allow
these flags regardless unless PTP_STRICT_FLAGS is also set.

If multicast snooping is enabled, multicast packets may not always end up
on the local bridge interface, if the host is not a member of the multicast
group. Similar to how IFF_PROMISC allows all packets to be received
locally, let IFF_ALLMULTI allow all multicast packets to be received.
OpenWrt uses a user space daemon for DHCPv6/RA/NDP handling, and in relay
mode it sets the ALLMULTI flag in order to receive all relevant queries on
the network.
This works for normal network interfaces and non-snooping bridges, but not
snooping bridges (unless multicast routing is enabled).

While developing the fix for the buffer sizing issue in [0], I noticed
that the kernel will happily accept a long list of actions for a filter,
and then just silently truncate that list down to a maximum of 32
actions.
That seems less than ideal, so this patch changes the action parsing to
return an error message and refuse to create the filter in this case.
This results in an error like:
# ip link add type veth
# tc qdisc replace dev veth0 root handle 1: fq_codel
# tc -echo filter add dev veth0 parent 1: u32 match u32 0 0 $(for i in $(seq 33); do echo action pedit munge ip dport set 22; done)
Error: Only 32 actions supported per filter.
We have an error talking to the kernel
Instead of just creating a filter with 32 actions and dropping the last
one.
This is obviously a change in UAPI. But seeing as creating more than 32
filters has never actually *worked*, it seems that returning an explicit
error is better, and any use cases that get broken by this were already
broken just in more subtle ways.

In order to do this, we need to make ingenic_mac_init() arguments

removed, and the PM ops pointer replaced with stmmac_pltfr_pm_ops.

Create a new helper function, nlmsg_payload(), to simplify checking and
retrieving Netlink message payloads.
This reduces boilerplate code for users who need to verify the message
length before accessing its data.

While most of the trace code is reachable by other routes
(I think mostly via the qed_features_lookup[] array), there
are a couple of unused wrappers.

mptcp_connect.c is a startup tutorial of MPTCP programming, however
there is a lack of ai_protocol(IPPROTO_MPTCP) usage. Add comment for
getaddrinfo MPTCP support.
This patch first uses IPPROTO_MPTCP to get addrinfo, and if glibc
version is too old, it falls back to using IPPROTO_TCP.

It's strange that 'nlh' variable is set to NULL in get_mptcpinfo() and then
this NULL pointer is passed to recv_nlmsg(). In fact, this variable should
be defined in recv_nlmsg(), not get_mptcpinfo().
So this patch drops this useless 'nlh' parameter of recv_nlmsg() and define
'nlh' variable in recv_nlmsg().

The parent commit adds this new counter, incremented when receiving a
connection request, if the PM didn't allow the creation of new subflows.
Most of the time, it is then kept at 0, except when the PM limits cause
the receiver side to reject new MPJoin connections. This is the case in
the following tests:
- single subflow, limited by server
- multiple subflows, limited by server
- subflows limited by server w cookies
- userspace pm type rejects join
- userspace pm type prevents mp_prio
Simply set join_syn_rej=1 when checking the MPJoin counters for these
tests.

This counter is useful to understand why some paths are rejected, and
not created as expected.
