Merge tag 'net-next-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to walk
all map elements in a more robust and easier to verify fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF on
s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets

- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks

- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices which don't
need headers in the linear skb part (e.g. virtio)

- nexthop: resilient next-hop groups - improve path stability on
next-hops group changes (incl. offload for mlxsw)

- ipv6: segment routing: add support for IPv4 decapsulation

- icmp: add support for RFC 8335 extended PROBE messages

- inet: use bigger hash table for IP ID generation

- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is slow in
reporting that it completed transmitting the original

- tcp: reorder tcp_congestion_ops for better cache locality

- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR
- add reset option support for resetting one subflow

- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take place
correctly even for encapsulated UDP traffic

- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO

- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls

- veth: allow GRO without XDP - this allows aggregating UDP packets
before handing them off to routing, bridge, OvS, etc.

- allow specifing ifindex when device is moved to another namespace

- netfilter:
- nft_socket: add support for cgroupsv2
- nftables: add catch-all set element - special element used to
define a default action in case normal lookup missed
- use net_generic infra in many modules to avoid allocating
per-ns memory unnecessarily

- xps: improve the xps handling to avoid potential out-of-bound
accesses and use-after-free when XPS change race with other
re-configuration under traffic

- add a config knob to turn off per-cpu netdev refcnt to catch
underflows in testing

Device APIs:

- add WWAN subsystem to organize the WWAN interfaces better and
hopefully start driving towards more unified and vendor-
independent APIs

- ethtool:
- add interface for reading IEEE MIB stats (incl. mlx5 and bnxt
support)
- allow network drivers to dump arbitrary SFP EEPROM data,
current offset+length API was a poor fit for modern SFP which
define EEPROM in terms of pages (incl. mlx5 support)

- act_police, flow_offload: add support for packet-per-second
policing (incl. offload for nfp)

- psample: add additional metadata attributes like transit delay for
packets sampled from switch HW (and corresponding egress and
policy-based sampling in the mlxsw driver)

- dsa: improve support for sandwiched LAGs with bridge and DSA

- netfilter:
- flowtable: use direct xmit in topologies with IP forwarding,
bridging, vlans etc.
- nftables: counter hardware offload support

- Bluetooth:
- improvements for firmware download w/ Intel devices
- add support for reading AOSP vendor capabilities
- add support for virtio transport driver

- mac80211:
- allow concurrent monitor iface and ethernet rx decap
- set priority and queue mapping for injected frames

- phy: add support for Clause-45 PHY Loopback

- pci/iov: add sysfs MSI-X vector assignment interface to distribute
MSI-X resources to VFs (incl. mlx5 support)

New hardware/drivers:

- dsa: mv88e6xxx: add support for Marvell mv88e6393x - 11-port
Ethernet switch with 8x 1-Gigabit Ethernet and 3x 10-Gigabit
interfaces.

- dsa: support for legacy Broadcom tags used on BCM5325, BCM5365 and
BCM63xx switches

- Microchip KSZ8863 and KSZ8873; 3x 10/100Mbps Ethernet switches

- ath11k: support for QCN9074 a 802.11ax device

- Bluetooth: Broadcom BCM4330 and BMC4334

- phy: Marvell 88X2222 transceiver support

- mdio: add BCM6368 MDIO mux bus controller

- r8152: support RTL8153 and RTL8156 (USB Ethernet) chips

- mana: driver for Microsoft Azure Network Adapter (MANA)

- Actions Semi Owl Ethernet MAC

- can: driver for ETAS ES58X CAN/USB interfaces

Pure driver changes:

- add XDP support to: enetc, igc, stmmac

- add AF_XDP support to: stmmac

- virtio:
- page_to_skb() use build_skb when there's sufficient tailroom
(21% improvement for 1000B UDP frames)
- support XDP even without dedicated Tx queues - share the Tx
queues with the stack when necessary

- mlx5:
- flow rules: add support for mirroring with conntrack, matching
on ICMP, GTP, flex filters and more
- support packet sampling with flow offloads
- persist uplink representor netdev across eswitch mode changes
- allow coexistence of CQE compression and HW time-stamping
- add ethtool extended link error state reporting

- ice, iavf: support flow filters, UDP Segmentation Offload

- dpaa2-switch:
- move the driver out of staging
- add spanning tree (STP) support
- add rx copybreak support
- add tc flower hardware offload on ingress traffic

- ionic:
- implement Rx page reuse
- support HW PTP time-stamping

- octeon: support TC hardware offloads - flower matching on ingress
and egress ratelimitting.

- stmmac:
- add RX frame steering based on VLAN priority in tc flower
- support frame preemption (FPE)
- intel: add cross time-stamping freq difference adjustment

- ocelot:
- support forwarding of MRP frames in HW
- support multiple bridges
- support PTP Sync one-step timestamping

- dsa: mv88e6xxx, dpaa2-switch: offload bridge port flags like
learning, flooding etc.

- ipa: add IPA v4.5, v4.9 and v4.11 support (Qualcomm SDX55, SM8350,
SC7280 SoCs)

- mt7601u: enable TDLS support

- mt76:
- add support for 802.3 rx frames (mt7915/mt7615)
- mt7915 flash pre-calibration support
- mt7921/mt7663 runtime power management fixes"
