Add a second device index, sdif, to udp socket lookups. sdif is the index for ingress devices enslaved to an l3mdev. It allows the lookups to consider the enslaved device as well as the L3 domain when searching for a socket. Early demux lookups are handled in the next patch as part of INET_MATCH changes.

Prior to tcp_v4_rcv (e.g., early demux) the ingress index is obtained from IPCB using inet_sdif and after the cb move in tcp_v4_rcv the tcp_v4_sdif helper is used. Signed-off-by:

Without CONFIG_PCI_IOV, we get a harmless warning about an unused function: drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c:2273:13: error: 'hclge_disable_sriov' defined but not used [-Werror=unused-function] The #ifdefs in this driver are obviously wrong, so this just removes them and uses an IS_ENABLED() check that does the same thing correctly in a more readable way.

Saeed Mahameed says: ==================== mlx5-shared-2017-08-07 This series includes some mlx5 updates for both net-next and rdma trees. From Saeed, Core driver updates to allow selectively building the driver with or without some large driver components, such as - E-Switch (Ethernet SRIOV support). - Multi-Physical Function Switch (MPFs) support. For that we split E-Switch and MPFs functionalities into separate files. From Erez, Delay mlx5_core events when mlx5 interfaces, namely mlx5_ib, registration is taking place and until it completes. From Rabie, Increase the maximum supported flow counters. ==================== Signed-off-by:

Jiri Pirko says: ==================== net: sched: summer cleanup part 2, ndo_setup_tc This patchset focuses on ndo_setup_tc and its args. Currently there are couple of things that do not make much sense. The type is passed in struct tc_to_netdev, but as it is always required, should be arg of the ndo. Other things are passed as args but they are only relevant for cls offloads and not mqprio. Therefore, they should be pushed to struct. As the tc_to_netdev struct in the end is just a container of single pointer, we get rid of it and pass the struct according to type. So in the end, we have: ndo_setup_tc(dev, type, type_data_struct) There are couple of cosmetics done on the way to make things smooth. Also, reported error is consolidated to eopnotsupp in case the asked offload is not supported. v1->v2: - added forgotten hns3pf bits ==================== Acked-by:

Read new NIC capability field which represnts 16 MSBs of the max flow counters number supported (max_flow_counter_31_16). Backward compatibility with older firmware is preserved, the modified driver reads max_flow_counter_31_16 as 0 from the older firmware and uses up to 64K counters. Changed flow counter id from 16 bits to 32 bits. Backward compatibility with older firmware is preserved as we kept the 16 LSBs of the counter id in place and added 16 MSBs from reserved field. Changed the background bulk reading of flow counters to work in chunks of at most 32K counters, to make sure we don't attempt to allocate very large buffers. Signed-off-by:

When mlx5_ib registers itself to mlx5_core as an interface, it will call mlx5_add_device which will call mlx5_ib interface add callback, in case the latter successfully returns, only then mlx5_core will add it to the interface list and async events will be forwarded to mlx5_ib. Between mlx5_ib interface add callback and mlx5_core adding the mlx5_ib interface to its devices list, arriving mlx5_core events can be missed by the new mlx5_ib registering interface. In other words: thread 1: mlx5_ib: mlx5_register_interface(dev) thread 1: mlx5_core: mlx5_add_device(dev) thread 1: mlx5_core: ctx = dev->add => (mlx5_ib)->mlx5_ib_add thread 2: mlx5_core_event: **new event arrives, forward to dev_list thread 1: mlx5_core: add_ctx_to_dev_list(ctx) /* previous event was missed by the new interface.*/ It is ok to miss events before dev->add (mlx5_ib)->mlx5_ib_add_device but not after. We fix this race by accumulating the events that come between the ib_register_device (inside mlx5_add_device->(dev->add)) till the adding to the list completes and fire them to the new registering interface after that.

Also remove the need of two ndo ops structures (sriov & basic) and keep only one unified ndo ops, compile out VF SRIOV ndos when not needed (MLX5_ESWITCH=n), and for VF netdev calling those ndos will result in returning -EPERM.

Multi-Physical Function Switch (MPFs) is required for when multi-PF configuration is enabled to allow passing user configured unicast MAC addresses to the requesting PF. Before this patch eswitch.c used to manage the HW MPFS l2 table, E-Switch always (regardless of sriov) enabled vport(0) (NIC PF) vport's contexts update on unicast mac address list changes, to populate the PF's MPFS L2 table accordingly. In downstream patch we would like to allow compiling the driver without E-Switch functionalities, for that we move MPFS l2 table logic out of eswitch.c into its own file, and provide Kconfig flag (MLX5_MPFS) to allow compiling out MPFS for those who don't want Multi-PF support. NIC PF netdevice will now directly update MPFS l2 table via the new MPFS API. VF netdevice has no access to MPFS L2 table, so E-Switch will remain responsible of updating its MPFS l2 table on behalf of its VFs. Due to this change we also don't require enabling vport(0) (PF vport) unicast mac changes events anymore, for when SRIOV is not enabled. Which means E-Switch is now activated only on SRIOV activation, and not required otherwise. Signed-off-by:
