Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski: "The sprinkling of SPI drivers is because we added a new one and Mark sent us a SPI driver interface conversion pull request.
Core ----
- Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout the stack.
- Switch netdev error counters from an atomic to dynamically allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF ---
- Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols ---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior.
- VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port. Support NS/NA monitor selection similar to existing ARP monitor.
- SMC - improve performance with TCP_CORK and sendfile() - support auto-corking - support TCP_NODELAY
- MCTP (Management Component Transport Protocol) - add user space tag control interface - I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth: - handle MSFT Monitor Device Event - add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP: - add support for the SO_SNDTIMEO socket option - lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API ----------
- Add HW counters for SW netdevs, a mechanism for devices which offload packet forwarding to report packet statistics back to software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of drivers to use that lock directly instead of creating their own which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling of TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture): - replay and offload of host VLAN entries - offload of static and local FDB entries on LAG interfaces - FDB isolation and unicast filtering

Merge branch 'dsa-realtek-MDIO'
Luiz Angelo Daros de Luca says:
==================== net: dsa: realtek: MDIO interface and RTL8367S,RTL8367RB-VB
The old realtek-smi driver was linking subdrivers into a single realtek-smi.ko After this series, each subdriver will be an independent module required by either realtek-smi (platform driver) or the new realtek-mdio (mdio driver). Both interface drivers (SMI or MDIO) are independent, and they might even work side-by-side, although it will be difficult to find such device. The subdriver can be individually selected but only at buildtime, saving some storage space for custom embedded systems.
Existing realtek-smi devices continue to work untouched during the tests. The realtek-smi was moved into a realtek subdirectory, but it normally does not break things.
I couldn't identify a fixed relation between port numbers (0..9) and external interfaces (0..2), and I'm not sure if it is fixed for each chip version or a device configuration. Until there is more info about it, there is a new port property "realtek,ext-int" that can inform the external interface.
The rtl8365mb might now handle multiple CPU ports and extint ports not used as CPU ports. RTL8367S has an SGMII external interface, but my test device (TP-Link Archer C5v4) uses only the second RGMII interface. We need a test device with more external ports to test these features. The driver still cannot handle SGMII ports.
RTL8367RB-VB support was added using information from Frank Wunderlich <frank-w@public-files.de> but I didn't test it myself.
The rtl8365mb was tested with a MDIO-connected RTL8367S (TP-Link Acher C5v4) and a SMI-connected RTL8365MB-VC switch (Asus RT-AC88U)
The rtl8366rb subdriver was not tested with this patch series, but it was only slightly touched. It would be nice to test it, especially in an MDIO-connected switch.
Best,
Luiz
Changelog:
v1-v2) - formatting fixes - dropped the rtl8365mb->rtl8367c rename - other suggestions
v2-v3) * realtek-mdio.c: - cleanup realtek-mdio.c (BUG_ON, comments and includes) - check devm_regmap_init return code - removed realtek,rtl8366s string from realtek-mdio * realtek-smi.c: - removed void* type cast * rtl8365mb.c: - using macros to identify EXT interfaces - rename some extra extport->extint cases - allow extint as non cpu (not tested) - allow multple cpu ports (not tested) - dropped cpu info from struct rtl8365mb * dropped dt-bindings changes (dealing outside this series) * formatting issues fixed
v3-v4) * fix cover message numbering 0/13 -> 0/11 * use static for realtek_mdio_read_reg - Reported-by: kernel test robot <lkp@intel.com> * use dsa_switch_for_each_cpu_port * mention realtek_smi_{variant,ops} to realtek_{variant,ops} in commit message
v5) sent again v4 branch. Sorry
v4-v6) - added support for RTL8367RB-VB - cleanup mdio_{read,write}, removing misterious START_OP, checking and returning errors - renamed priv->phy_id to priv->mdio_addr - duplicated priv->ds_ops into ds_ops_{smi,mdio}. ds_ops_smi must not set phy_read or else both dsa and this driver might free slave_mii. Dropped 401fd75c92f37 - Map port to extint using code instead of device-tree property. Added comment about port number, port description and external interfaces. Dropped 'realtek,ext-int' device-tree property - Redacted the non-cpu ext port commit message, not highlighting the possibility of using multiple CPU ports as it was just a byproduct. - In a possible case of multiple cpu ports, use the first one as the trap port. Dropped 'realtek,trap-port' device-tree property - Some formatting fixes - BUG: rtl8365mb_phy_mode_supported was still checking for a cpu port and not an external interface - BUG: fix trapdoor masking for port>7. Got a compiler error with a bigger constant value - WARN: completed kdoc for rtl8366rb_drop_untagged() - WARN: removed marks from incomplete kdoc ====================

net: dsa: realtek: add new mdio interface for drivers
This driver is a mdio_driver instead of a platform driver (like realtek-smi).
ds_ops was duplicated for smi and mdio usage as mdio interfaces uses phy_{read,write} in ds_ops and the presence of phy_read is incompatible with external slave_mii_bus allocation.
