====================
This series includes a couple of fixups for the IPv6 socket lookup
helper, to make the API more consistent (always supply all arguments in
network byte-order) and to allow its use when IPv6 is compiled as a
module.

Commit 6acc9b432e67 ("bpf: Add helper to retrieve socket in BPF")
mistakenly passed the destination port in network byte-order to the IPv6
TCP/UDP socket lookup functions, which meant that BPF writers would need
to either manually swap the byte-order of this field or otherwise IPv6
sockets could not be located via this helper.
Fix the issue by swapping the byte-order appropriately in the helper.
This also makes the API more consistent with the IPv4 version.

This is a more complete fix than d71019b54bff ("net: core: Fix build

Daniel Borkmann says:
====================
This work adds a generic sk_msg layer and converts both sockmap
and later ktls over to make use of it as a common data structure
for application data (similarly as sk_buff for network packets).
With that in place the sk_msg framework spans accross ULP layer
in the kernel and allows for introspection or filtering of L7
data with the help of BPF programs operating on a common input
context.
In a second step, we enable the latter for ktls which was previously
not possible, meaning, ktls and sk_msg verdict programs were
mutually exclusive in the ULP layer which created challenges for
the orchestrator when trying to apply TCP based policy, for
example. Leveraging the prior consolidation we can finally overcome
this limitation.
Note, there's no change in behavior when ktls is not used in
combination with BPF, and also no change in behavior for stand
alone sockmap. The kselftest suites for ktls, sockmap and ktls
with sockmap combined also runs through successfully. For further
details please see individual patches.
Thanks!
v1 -> v2:
- Removed leftover comment spotted by Alexei
- Improved commit messages, rebase

This work adds BPF sk_msg verdict program support to kTLS
allowing BPF and kTLS to be combined together. Previously kTLS
and sk_msg verdict programs were mutually exclusive in the
ULP layer which created challenges for the orchestrator when
trying to apply TCP based policy, for example. To resolve this,
leveraging the work from previous patches that consolidates
the use of sk_msg, we can finally enable BPF sk_msg verdict
programs so they continue to run after the kTLS socket is
created. No change in behavior when kTLS is not used in
combination with BPF, the kselftest suite for kTLS also runs
successfully.

Instead of re-implementing poll routine use the poll callback to
trigger read from kTLS, we reuse the stream_memory_read callback
which is simpler and achieves the same. This helps to align sockmap
and kTLS so we can more easily embed BPF in kTLS.

Convert kTLS over to make use of sk_msg interface for plaintext and
encrypted scattergather data, so it reuses all the sk_msg helpers
and data structure which later on in a second step enables to glue
this to BPF.
This also allows to remove quite a bit of open coded helpers which
are covered by the sk_msg API. Recent changes in kTLs 80ece6a03aaf
("tls: Remove redundant vars from tls record structure") and
4e6d47206c32 ("tls: Add support for inplace records encryption")
changed the data path handling a bit; while we've kept the latter
optimization intact, we had to undo the former change to better
fit the sk_msg model, hence the sg_aead_in and sg_aead_out have
been brought back and are linked into the sk_msg sgs. Now the kTLS
record contains a msg_plaintext and msg_encrypted sk_msg each.
In the original code, the zerocopy_from_iter() has been used out
of TX but also RX path. For the strparser skb-based RX path,
we've left the zerocopy_from_iter() in decrypt_internal() mostly
untouched, meaning it has been moved into tls_setup_from_iter()
with charging logic removed (as not used from RX). Given RX path
is not based on sk_msg objects, we haven't pursued setting up a
dummy sk_msg to call into sk_msg_zerocopy_from_iter(), but it
could be an option to prusue in a later step.

Add a generic sk_msg layer, and convert current sockmap and later
kTLS over to make use of it. While sk_buff handles network packet
representation from netdevice up to socket, sk_msg handles data
representation from application to socket layer.
This means that sk_msg framework spans across ULP users in the
kernel, and enables features such as introspection or filtering
of data with the help of BPF programs that operate on this data
structure.
Latter becomes in particular useful for kTLS where data encryption
is deferred into the kernel, and as such enabling the kernel to
perform L7 introspection and policy based on BPF for TLS connections
where the record is being encrypted after BPF has run and came to
a verdict. In order to get there, first step is to transform open
coding of scatter-gather list handling into a common core framework
that subsystems can use.
The code itself has been split and refactored into three bigger
pieces: i) the generic sk_msg API which deals with managing the
scatter gather ring, providing helpers for walking and mangling,
transferring application data from user space into it, and preparing
it for BPF pre/post-processing, ii) the plain sock map itself
where sockets can be attached to or detached from; these bits
are independent of i) which can now be used also without sock
map, and iii) the integration with plain TCP as one protocol
to be used for processing L7 application data (later this could
e.g. also be extended to other protocols like UDP). The semantics
are the same with the old sock map code and therefore no change
of user facing behavior or APIs. While pursuing this work it
also helped finding a number of bugs in the old sockmap code
that we've fixed already in earlier commits. The test_sockmap
kselftest suite passes through fine as well.

A couple of macros that deal with statistics in ath9k rely on the
declaration of the 'sc' variable, which they dereference.
However, when the statistics are disabled, the new instance in
ath_cmn_process_fft() causes a warning for an unused variable:
drivers/net/wireless/ath/ath9k/common-spectral.c: In function 'ath_cmn_process_fft':
drivers/net/wireless/ath/ath9k/common-spectral.c:474:20: error: unused variable 'sc' [-Werror=unused-variable]
It's better if those macros only operate on their arguments instead of
known variable names, and adding a cast to (void) kills off that warning.

ath10k_pci_diag_write_mem may allocate big size of the dma memory
based on the parameter nbytes. Take firmware diag download as
example, the biggest size is about 500K. In some systems, the
allocation is likely to fail because it can't acquire such a large
contiguous dma memory.
The fix is to allocate a small size dma memory. In the loop,
driver copies the data to the allocated dma memory and writes to
the destination until all the data is written.

* wake up on network detection, up to 16 match sets
And it can be enabled with command:

Firmware will do scan by the configured parameters after suspend and

Introduce phy/vco temperature calibration.
Moreover fix configuration of register 67 on bank0
during temperature reading and use mt76_poll utility routine
to poll core34 register.
Furthermore temperature compensation needs to be disabled
if the device supports tssi compensation.
This issue has never been hit since temperature reading is not
actually used by usb code.

Add mt76x0_tssi_enabled in order to check if tssi compensation
is enabled since mt76x0 condition differs from mt76x2 one.
Moreover move back mt76x02_temp_tx_alc_enabled and mt76x02_tssi_enabled
routines in mt76x2/eeprom.h since they are mt76x2 specific

mt76x0_phy_set_channel function.
