Currently, WQE and EQE table have already used the mtr interface to config and access memory by multi-hop addressing when hopnum is from 1 to 3. But if hopnum is 0, each table need write its own but repetitive logic, and many duplicate code exists in the mtr interfaces invoke process. So wraps the public logic as 3 functions: hns_roce_mtr_create(), hns_roce_mtr_destroy() and hns_roce_mtr_map() to support hopnum ranges from 0 to 3. In addition, makes the mtr interfaces easier to use.

This cycle saw some more activity from Syzkaller, I think we are now clean on all but one of those bugs, including the long standing and obnoxious rdma_cm locking design defect. Continue to see many drivers getting cleanups, with a few new user visible features. Summary: - Various driver updates for siw, bnxt_re, rxe, efa, mlx5, hfi1 - Lots of cleanup patches for hns - Convert more places to use refcount - Aggressively lock the RDMA CM code that syzkaller says isn't working - Work to clarify ib_cm - Use the new ib_device lifecycle model in bnxt_re - Fix mlx5's MR cache which seems to be failing more often with the new ODP code - mlx5 'dynamic uar' and 'tx steering' user interfaces" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (144 commits) RDMA/bnxt_re: make bnxt_re_ib_init static IB/qib: Delete struct qib_ivdev.qp_rnd RDMA/hns: Fix uninitialized variable bug RDMA/hns: Modify the mask of QP number for CQE of hip08 RDMA/hns: Reduce the maximum number of extend SGE per WQE RDMA/hns: Reduce PFC frames in congestion scenarios RDMA/mlx5: Add support for RDMA TX flow table net/mlx5: Add support for RDMA TX steering IB/hfi1: Call kobject_put() when kobject_init_and_add() fails IB/hfi1: Fix memory leaks in sysfs registration and unregistration IB/mlx5: Move to fully dynamic UAR mode once user space supports it IB/mlx5: Limit the scope of struct mlx5_bfreg_info to mlx5_ib IB/mlx5: Extend QP creation to get uar page index from user space IB/mlx5: Extend CQ creation to get uar page index from user space IB/mlx5: Expose UAR object and its alloc/destroy commands IB/hfi1: Get rid of a warning RDMA/hns: Remove redundant judgment of qp_type RDMA/hns: Remove redundant assignment of wc->smac when polling cq RDMA/hns: Remove redundant qpc setup operations RDMA/hns: Remove meaningless prints ...

Pull networking updates from David Miller: "Highlights: 1) Fix the iwlwifi regression, from Johannes Berg. 2) Support BSS coloring and 802.11 encapsulation offloading in hardware, from John Crispin. 3) Fix some potential Spectre issues in qtnfmac, from Sergey Matyukevich. 4) Add TTL decrement action to openvswitch, from Matteo Croce. 5) Allow paralleization through flow_action setup by not taking the RTNL mutex, from Vlad Buslov. 6) A lot of zero-length array to flexible-array conversions, from Gustavo A. R. Silva. 7) Align XDP statistics names across several drivers for consistency, from Lorenzo Bianconi. 8) Add various pieces of infrastructure for offloading conntrack, and make use of it in mlx5 driver, from Paul Blakey. 9) Allow using listening sockets in BPF sockmap, from Jakub Sitnicki. 10) Lots of parallelization improvements during configuration changes in mlxsw driver, from Ido Schimmel. 11) Add support to devlink for generic packet traps, which report packets dropped during ACL processing. And use them in mlxsw driver. From Jiri Pirko. 12) Support bcmgenet on ACPI, from Jeremy Linton. 13) Make BPF compatible with RT, from Thomas Gleixnet, Alexei Starovoitov, and your's truly. 14) Support XDP meta-data in virtio_net, from Yuya Kusakabe. 15) Fix sysfs permissions when network devices change namespaces, from Christian Brauner. 16) Add a flags element to ethtool_ops so that drivers can more simply indicate which coalescing parameters they actually support, and therefore the generic layer can validate the user's ethtool request. Use this in all drivers, from Jakub Kicinski. 17) Offload FIFO qdisc in mlxsw, from Petr Machata. 18) Support UDP sockets in sockmap, from Lorenz Bauer. 19) Fix stretch ACK bugs in several TCP congestion control modules, from Pengcheng Yang. 20) Support virtual functiosn in octeontx2 driver, from Tomasz Duszynski. 21) Add region operations for devlink and use it in ice driver to dump NVM contents, from Jacob Keller. 22) Add support for hw offload of MACSEC, from Antoine Tenart. 23) Add support for BPF programs that can be attached to LSM hooks, from KP Singh. 24) Support for multiple paths, path managers, and counters in MPTCP. From Peter Krystad, Paolo Abeni, Florian Westphal, Davide Caratti, and others. 25) More progress on adding the netlink interface to ethtool, from Michal Kubecek" * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2121 commits) net: ipv6: rpl_iptunnel: Fix potential memory leak in rpl_do_srh_inline cxgb4/chcr: nic-tls stats in ethtool net: dsa: fix oops while probing Marvell DSA switches net/bpfilter: remove superfluous testing message net: macb: Fix handling of fixed-link node net: dsa: ksz: Select KSZ protocol tag netdevsim: dev: Fix memory leak in nsim_dev_take_snapshot_write net: stmmac: add EHL 2.5Gbps PCI info and PCI ID net: stmmac: add EHL PSE0 & PSE1 1Gbps PCI info and PCI ID net: stmmac: create dwmac-intel.c to contain all Intel platform net: dsa: bcm_sf2: Support specifying VLAN tag egress rule net: dsa: bcm_sf2: Add support for matching VLAN TCI net: dsa: bcm_sf2: Move writing of CFP_DATA(5) into slicing functions net: dsa: bcm_sf2: Check earlier for FLOW_EXT and FLOW_MAC_EXT net: dsa: bcm_sf2: Disable learning for ASP port net: dsa: b53: Deny enslaving port 7 for 7278 into a bridge net: dsa: b53: Prevent tagged VLAN on port 7 for 7278 net: dsa: b53: Restore VLAN entries upon (re)configuration net: dsa: bcm_sf2: Fix overflow checks hv_netvsc: Remove unnecessary round_up for recv_completion_cnt ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull EFI updates from Ingo Molnar: "The EFI changes in this cycle are much larger than usual, for two (positive) reasons: - The GRUB project is showing signs of life again, resulting in the introduction of the generic Linux/UEFI boot protocol, instead of x86 specific hacks which are increasingly difficult to maintain. There's hope that all future extensions will now go through that boot protocol. - Preparatory work for RISC-V EFI support. The main changes are: - Boot time GDT handling changes - Simplify handling of EFI properties table on arm64 - Generic EFI stub cleanups, to improve command line handling, file I/O, memory allocation, etc. - Introduce a generic initrd loading method based on calling back into the firmware, instead of relying on the x86 EFI handover protocol or device tree. - Introduce a mixed mode boot method that does not rely on the x86 EFI handover protocol either, and could potentially be adopted by other architectures (if another one ever surfaces where one execution mode is a superset of another) - Clean up the contents of 'struct efi', and move out everything that doesn't need to be stored there. - Incorporate support for UEFI spec v2.8A changes that permit firmware implementations to return EFI_UNSUPPORTED from UEFI runtime services at OS runtime, and expose a mask of which ones are supported or unsupported via a configuration table. - Partial fix for the lack of by-VA cache maintenance in the decompressor on 32-bit ARM. - Changes to load device firmware from EFI boot service memory regions - Various documentation updates and minor code cleanups and fixes" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (114 commits) efi/libstub/arm: Fix spurious message that an initrd was loaded efi/libstub/arm64: Avoid image_base value from efi_loaded_image partitions/efi: Fix partition name parsing in GUID partition entry efi/x86: Fix cast of image argument efi/libstub/x86: Use ULONG_MAX as upper bound for all allocations efi: Fix a mistype in comments mentioning efivar_entry_iter_begin() efi/libstub: Avoid linking libstub/lib-ksyms.o into vmlinux efi/x86: Preserve %ebx correctly in efi_set_virtual_address_map() efi/x86: Ignore the memory attributes table on i386 efi/x86: Don't relocate the kernel unless necessary efi/x86: Remove extra headroom for setup block efi/x86: Add kernel preferred address to PE header efi/x86: Decompress at start of PE image load address x86/boot/compressed/32: Save the output address instead of recalculating it efi/libstub/x86: Deal with exit() boot service returning x86/boot: Use unsigned comparison for addresses efi/x86: Avoid using code32_start efi/x86: Make efi32_pe_entry() more readable efi/x86: Respect 32-bit ABI in efi32_pe_entry() efi/x86: Annotate the LOADED_IMAGE_PROTOCOL_GUID with SYM_DATA ...
