Merge tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:

- Add redirect_neigh() BPF packet redirect helper, allowing to limit
stack traversal in common container configs and improving TCP
back-pressure.

Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.

- Expand netlink policy support and improve policy export to user
space. (Ge)netlink core performs request validation according to
declared policies. Expand the expressiveness of those policies
(min/max length and bitmasks). Allow dumping policies for particular
commands. This is used for feature discovery by user space (instead
of kernel version parsing or trial and error).

- Support IGMPv3/MLDv2 multicast listener discovery protocols in
bridge.

- Allow more than 255 IPv4 multicast interfaces.

- Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
packets of TCPv6.

- In Multi-patch TCP (MPTCP) support concurrent transmission of data on
multiple subflows in a load balancing scenario. Enhance advertising
addresses via the RM_ADDR/ADD_ADDR options.

- Support SMC-Dv2 version of SMC, which enables multi-subnet
deployments.

- Allow more calls to same peer in RxRPC.

- Support two new Controller Area Network (CAN) protocols - CAN-FD and
ISO 15765-2:2016.

- Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
kernel problem.

- Add TC actions for implementing MPLS L2 VPNs.

- Improve nexthop code - e.g. handle various corner cases when nexthop
objects are removed from groups better, skip unnecessary
notifications and make it easier to offload nexthops into HW by
converting to a blocking notifier.

- Support adding and consuming TCP header options by BPF programs,
opening the doors for easy experimental and deployment-specific TCP
option use.

- Reorganize TCP congestion control (CC) initialization to simplify
life of TCP CC implemented in BPF.

- Add support for shipping BPF programs with the kernel and loading
them early on boot via the User Mode Driver mechanism, hence reusing
all the user space infra we have.

- Support sleepable BPF programs, initially targeting LSM and tracing.

- Add bpf_d_path() helper for returning full path for given 'struct
path'.

- Make bpf_tail_call compatible with bpf-to-bpf calls.

- Allow BPF programs to call map_update_elem on sockmaps.

- Add BPF Type Format (BTF) support for type and enum discovery, as
well as support for using BTF within the kernel itself (current use
is for pretty printing structures).

- Support listing and getting information about bpf_links via the bpf
syscall.

- Enhance kernel interfaces around NIC firmware update. Allow
specifying overwrite mask to control if settings etc. are reset
during update; report expected max time operation may take to users;
support firmware activation without machine reboot incl. limits of
how much impact reset may have (e.g. dropping link or not).

- Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.

- Adopt or extend devlink use for debug, monitoring, fw update in many
drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx,
dpaa2-eth).

- In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.

- Add XDP support for Intel's igb driver.

- Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.

- Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.

- Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.

- Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.

- Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.

- Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.

- Improve performance for packets which don't require much offloads on
recent Mellanox NICs by 20% by making multiple packets share a
descriptor entry.

- Move chelsio inline crypto drivers (for TLS and IPsec) from the
crypto subtree to drivers/net. Move MDIO drivers out of the phy
directory.

- Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.

- Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

====================
wireless-drivers-next patches for v5.10

First set of patches for v5.10. Most noteworthy here is ath11k getting
initial support for QCA6390 and IPQ6018 devices. But most of the
patches are cleanup: W=1 warning fixes, fallthrough keywords, DMA API
changes and tasklet API changes.

Major changes:

ath10k

* support SDIO firmware codedumps

* support station specific TID configurations

ath11k

* add support for IPQ6018

* add support for QCA6390 PCI devices

ath9k

* add support for NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to improve PTK0
rekeying

* add support for TX ack
