Pull networking updates from David Miller: 1) Allow setting bluetooth L2CAP modes via socket option, from Luiz Augusto von Dentz. 2) Add GSO partial support to igc, from Sasha Neftin. 3) Several cleanups and improvements to r8169 from Heiner Kallweit. 4) Add IF_OPER_TESTING link state and use it when ethtool triggers a device self-test. From Andrew Lunn. 5) Start moving away from custom driver versions, use the globally defined kernel version instead, from Leon Romanovsky. 6) Support GRO vis gro_cells in DSA layer, from Alexander Lobakin. 7) Allow hard IRQ deferral during NAPI, from Eric Dumazet. 8) Add sriov and vf support to hinic, from Luo bin. 9) Support Media Redundancy Protocol (MRP) in the bridging code, from Horatiu Vultur. 10) Support netmap in the nft_nat code, from Pablo Neira Ayuso. 11) Allow UDPv6 encapsulation of ESP in the ipsec code, from Sabrina Dubroca. Also add ipv6 support for espintcp. 12) Lots of ReST conversions of the networking documentation, from Mauro Carvalho Chehab. 13) Support configuration of ethtool rxnfc flows in bcmgenet driver, from Doug Berger. 14) Allow to dump cgroup id and filter by it in inet_diag code, from Dmitry Yakunin. 15) Add infrastructure to export netlink attribute policies to userspace, from Johannes Berg. 16) Several optimizations to sch_fq scheduler, from Eric Dumazet. 17) Fallback to the default qdisc if qdisc init fails because otherwise a packet scheduler init failure will make a device inoperative. From Jesper Dangaard Brouer. 18) Several RISCV bpf jit optimizations, from Luke Nelson. 19) Correct the return type of the ->ndo_start_xmit() method in several drivers, it's netdev_tx_t but many drivers were using 'int'. From Yunjian Wang. 20) Add an ethtool interface for PHY master/slave config, from Oleksij Rempel. 21) Add BPF iterators, from Yonghang Song. 22) Add cable test infrastructure, including ethool interfaces, from Andrew Lunn. Marvell PHY driver is the first to support this facility. 23) Remove zero-length arrays all over, from Gustavo A. R. Silva. 24) Calculate and maintain an explicit frame size in XDP, from Jesper Dangaard Brouer. 25) Add CAP_BPF, from Alexei Starovoitov. 26) Support terse dumps in the packet scheduler, from Vlad Buslov. 27) Support XDP_TX bulking in dpaa2 driver, from Ioana Ciornei. 28) Add devm_register_netdev(), from Bartosz Golaszewski. 29) Minimize qdisc resets, from Cong Wang. 30) Get rid of kernel_getsockopt and kernel_setsockopt in order to eliminate set_fs/get_fs calls.

2020-06-03RDMA/mlx5: Return ECE DC supportLeon Romanovsky1-14/+31
The DC QPs are many-to-one QP types that means that first connection will establish ECE options that coming connections should follow. Due to this property, the ECE code was removed between first [1] and second [2] ECE submissions. This patch returns the dropped code, because ECE is a property of a connection and like any other connection users are needed to manage this data. Allow them to set ECE parameter for DC too and avoid need of having compatibility flag for the DC ECE.

2020-05-29RDMA/mlx5: Support TX port affinity for VF drivers in LAG modeMark Zhang3-2/+10
The mlx5 VF driver doesn't set QP tx port affinity because it doesn't know if the lag is active or not, since the "lag_active" works only for PF interfaces. In this case for VF interfaces only one lag is used which brings performance issue. Add a lag_tx_port_affinity CAP bit; When it is enabled and "num_lag_ports > 1", then driver always set QP tx affinity, regardless of lag state.

2020-05-22RDMA/mlx5: Fix NULL pointer dereference in destroy_prefetch_workMaor Gottlieb1-0/+1
q_deferred_work isn't initialized when creating an explicit ODP memory region. This can lead to a NULL pointer dereference when user performs asynchronous prefetch MR.

2020-05-22RDMA/core: Allow the ioctl layer to abort a fully created uobjectJason Gunthorpe3-32/+15
While creating a uobject every create reaches a point where the uobject is fully initialized. For ioctls that go on to copy_to_user this means they need to open code the destruction of a fully created uobject - ie the RDMA_REMOVE_DESTROY sort of flow. Open coding this creates bugs, eg the CQ does not properly flush the events list when it does its error unwind. Provide a uverbs_finalize_uobj_create() function which indicates that the uobject is fully initialized and that abort should call to destroy_hw to destroy the uobj->object and related. Methods can call this function if they go on to have error cases after setting uobj->object. Once done those error cases can simply do return, without an error unwind.
