When using the out-of-band WAKE_IN and WAKE_OUT pins, we have to tell
the firmware which pins to use (from controller point of view). This
allows to report remote wakeup support when WAKE_OUT(c2h) is configured.

Do not set 'HCI_UART_PROTO_READY' before call 'hci_uart_register_dev()'.
Possible race is when someone calls 'hci_tty_uart_close()' after this bit
is set, but 'hci_uart_register_dev()' wasn't done. This leads to access
to uninitialized fields. To fix it let's set this bit after device was
registered (as before patch c411c62cc133) and to fix previous problem let's
add one more bit in addition to 'HCI_UART_PROTO_READY' which allows to
perform power up without original bit set (pls see commit c411c62cc133).

'hci_register_dev()' calls power up function, which is executed by
kworker - 'hci_power_on()'. This function does access to bluetooth chip
using callbacks from 'hci_ldisc.c', for example 'hci_uart_send_frame()'.
Now 'hci_uart_send_frame()' checks 'HCI_UART_PROTO_READY' bit set, and
if not - it fails. Problem is that 'HCI_UART_PROTO_READY' is set after
'hci_register_dev()', and there is tiny chance that 'hci_power_on()' will
be executed before setting this bit. In that case HCI init logic fails.
Patch moves setting of 'HCI_UART_PROTO_READY' before calling function
'hci_uart_register_dev()'.

PHYs that are within copper SFP modules have their MDIO bus accessible
through address 0x56 (usually) on the i2c bus. The MDIO-I2C bridge is
desgned for 16 bits accesses, but we can also perform 8bits accesses by
reading/writing the high and low bytes sequentially.
This commit adds support for this type of accesses, thus supporting
smbus controllers such as the one in the VSC8552.
This was only tested on Copper SFP modules that embed a Marvell 88e1111
PHY.

The SFP module's eeprom and internals are accessible through an i2c bus.
It is possible that the SFP might be connected to an SMBus-only
controller, such as the one found in some PHY devices in the VSC85xx
family.
Introduce a set of sfp read/write ops that are going to be used if the
i2c bus is only capable of doing smbus byte accesses.
As Single-byte SMBus transaction go against SFF-8472 and breaks the
atomicity for diagnostics data access, hwmon is disabled in the case
of SMBus access.
Moreover, as this may cause other instabilities, print a warning at
probe time to indicate that the setup may be unreliable because of the
hardware design.
As hwmon may be disabled for both broken EEPROM and smbus, the warnings
are udpated accordingly.

DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.
No functional changes here, but saves some comments during reviews of
new patches built on existing code.

1) Use kvmalloc in xt_hashlimit, from Denis Kirjanov.
2) Tighten nf_conntrack sysctl accepted values for nf_conntrack_max
and nf_ct_expect_max, from Nicolas Bouchinet.
3) Avoid lookup in nft_fib if socket is available, from Florian Westphal.
4) Initialize struct lsm_context in nfnetlink_queue to avoid
hypothetical ENOMEM errors, Chenyuan Yang.
5) Use strscpy() instead of _pad when initializing xtables table name,
kzalloc is already used to initialized the table memory area.
From Thorsten Blum.
6) Missing socket lookup by conntrack information for IPv6 traffic
in nft_socket, there is a similar chunk in IPv4, this was never
added when IPv6 NAT was introduced. From Maxim Mikityanskiy.
7) Fix clang issues with nf_tables CONFIG_MITIGATION_RETPOLINE,

RFS is using two kinds of hash tables.
First one is controlled by /proc/sys/net/core/rps_sock_flow_entries = 2^N
and using the N low order bits of the l4 hash is good enough.
Then each RX queue has its own hash table, controlled by
/sys/class/net/eth1/queues/rx-$q/rps_flow_cnt = 2^X
Current hash function, using the X low order bits is suboptimal,
because RSS is usually using Func(hash) = (hash % power_of_two);
For example, with 32 RX queues, 6 low order bits have no entropy
for a given queue.
Switch this hash function to hash_32(hash, log) to increase
chances to use all possible slots and reduce collisions.

Previously, when the driver was printing hex dumps, the buffer was cast
to an 8 byte long and printed using string formatters. If the buffer
size was not a multiple of 8 then a read buffer overflow was possible.

Some bond modes (broadcast, etc.) do not support native xdp. Set bond mode

Russell King says:
====================
net: improve stmmac resume rx clocking
stmmac has had a long history of problems with resuming, illustrated by
reset failure due to the receive clock not running.
Several attempts have been attempted over the years to address this
issue, such as moving phylink_start() (now phylink_resume()) super
early in stmmac_resume() in commit 90702dcd19c0 ("net: stmmac: fix MAC
not working when system resume back with WoL a ctive.") However, this
has the downside that stmmac_mac_link_up() can (and demonstrably is)
called before or during the driver initialisation in another thread.
This can cause issues as packets could begin to be queued, and the
transmit/receive enable bits will be set before any initialisation has
been done.
Another attempt is used by dwmac-socfpga.c in commit 2d871aa07136 ("net:
stmmac: add platform init/exit for Altera's ARM socfpga") which
pre-dates the above commit.
Neither of these two approaches consider the effect of EEE with a PHY
that supports receive clock-stop and has that feature enabled (which
the stmmac driver does enable). If the link is up, then there is the
possibility for the receive path to be in low-power mode, and the PHY
may stop its receive clock.
This series addresses these issues by (each is not necessarily a
separate patch):
1) introducing phylink_prepare_resume(), which can be used by MAC
drivers to ensure that the PHY is resumed prior to doing any
re-initialisation work. This call is added to stmmac_resume().
2) moving phylink_resume() after all re-initialisation has completed,
thereby ensuring that the hardware is ready to be enabled for
packet reception/transmission.
3) with (1) and (2) addressed, the need for socfpga to have a private
work-around is no longer necessary, so it is removed.
4) introducing phylink functions to block/unblock the receive clock-
stop at the PHY. As these require PHY access over the MDIO bus,
they can sleep, so are not suitable for atomic access.
5) the stmmac hardware requires the receive clock to be running for
reset to complete. Depending on synthesis options, this requirement
may also extend to writing various registers as well, e.g. setting
the MAC address, writing some of the vlan registers, etc. Full
details are in the databook.
We add blocking/unblocking of the PHY receive clock-stop around
parts of the main stmmac driver where we have a context that we
can sleep. These are wrapped with the new phylink functions.
However, depending on synthesis options, there could be other
places where the net core calls the driver with a BH-disabled
context where we can't sleep, and thus can't block the PHY from
disabling its receive clock. These are documented with FIXME
comments.
Given the last paragraph above, I am wondering whether a better
approach would be to ensure that receive clock-stop is always disabled
at the PHY with stmmac. From what I can see, implementations do not
document to this level of detail, which makes it difficult to tell
which registers require the receive clock to be running to behave
correctly.
This patch series has been tested on the Tegra194 Jetson Xavier NX
board kindly donated by NVidia, with two additional patches that are
pending in patchwork - the first is required to have EEE's LPI mode
passed through to the MAC on this platform to allow testing under
PHY clock-stop scenarios. The second is a bug fix for PHYLIB and
makes "eee off" functional, but should not affect this series.

The DesignWare core requires the receive clock to be running during
certain operations. Ensure that we block PHY RXC clock-stop during
these operations.
This is a best-efforts change - not everywhere can be covered by this
because of net's core locking, which means we can't access the MDIO
bus to configure the PHY to disable RXC clock-stop in certain areas.
These are marked with FIXME comments.

Some MACs require the PHY receive clock to be running to complete setup
actions. This may fail if the PHY has negotiated EEE, the MAC supports
receive clock stop, and the link has entered LPI state. Provide a pair
of APIs that MAC drivers can use to temporarily block the PHY disabling
the receive clock.

The Synopsys Designware GMAC core databook requires all clocks to be
active in order to complete software reset, which we perform during
resume.
However, IEEE 802.3 allows a PHY to stop its clocks when placed in
low-power mode, which happens when the system is suspended and WoL
is not enabled.
As an attempt to work around this, commit 36d18b5664ef ("net: stmmac:
start phylink instance before stmmac_hw_setup()") started phylink
early, but this has the side effect that the mac_link_up() method may
be called before or during the initialisation of GMAC hardware.
We also have the socfpga glue driver directly calling phy_resume()
also as an attempt to work around this.
In a previous commit, phylink_prepare_resume() has been introduced
to give MAC drivers a way to ensure that the PHY is resumed prior to
their initialisation of their MAC hardware. This commit adds the call,
and moves the phylink_resume() call back to where it should be before
the aforementioned commit.
