BlueField device can be presented in one out of two modes: - SEPARATED_HOST: ARM processors as a separated and orthogonal host like any other external host in the multi-host virtualization model. - EMBEDDED_CPU: ARM processors as Embedded CPU (EC) and part of the external hosts virtualization model. While existing driver already supports the device on separated_host mode, this patch series focus on the functionalities of embedded_cpu mode. On embedded_cpu mode, BlueField device exposes regular network controller PCI function in the BlueField host(e.g, x86). However, a separate PCI function called Embedded CPU Physical Function(ECPF) is also added to the ARM host side, where standard Linux distributions is able to run on the ARM cores. Depends on the NV configuration from firmware, ECPF can be the e-switch manager and firmware pages supplier. If ECPF is configured as e-switch manager and page supplier, it will take over the responsibilities from the PF on BlueField host includes: - Owns, controls and manages all e-switch parts, and takes e-switch traffic by default. It also should perform ENABLE_HCA for the host PF just like a PF does for its VFs. - Provides and manages the ICM host memory required for the HCA to store various contexts for itself, the PF and VFs belong the e-switch it manages. The PF on BlueField host side is still responsible for: - Control its own permanent MAC. - PCI and SRIOV configurations and perform ENABLE_HCA for its VFs. The ECPF can also retrieve information about the external host it controls, like host identifier, PCI BDF and number of virtual functions. As these parameters may be changed dynamically, an event will be triggered to the driver on ECPF side. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-02-15net/mlx5: E-Switch, Allow transition to offloads mode for ECPFBodong Wang
Currently, the e-switch driver requires going to legacy mode before changing to the offloads mode. This makes sense for regular case as the legacy mode is done by creating VFs. However, it's problematic when ECPF is the eswitch manager. In such case, ECPF will control the vports on peer host including the peer PF and VFs. But ECPF doesn't need and shall not create VFs as the VFs are created in the peer PF host. Grant ECPF the ability to change from none to the offloads mode. Note that currently the only way to go back to none mode is by unloading the ECPF driver.

2019-02-15net/mlx5: E-Switch, Load/unload VF reps according to event from host PFBodong Wang
When host PF changes the number of VFs, the ECPF esw driver will get a FW event. It should query the number of VFs enabled by host PF and update the VF reps accordingly. Note that host PF can't change the number of VFs dynamically, it has to reset the number of VFs to 0 before changing to a new positive number. The host event is registered when driver is moving to switchdev mode, and it's the last step to do in esw_offloads_init. It's unregistered and the work queue is flushed when driver quits from switchdev mode. In this way, the host event and devlink command are serialized. When driver is enabling switchdev mode, pay attention to the following two facts: 1. Host PF must not have VF initialized as the flow table in ECPF has ENCAP enabled as default. Such flow table can't be created with existing initialized VFs. 2. ECPF doesn't know how many VFs the host PF will enable, ECPF offloads flow steering shall create the flow table/groups based on the max number of VFs possibly supported by host PF.

2019-02-15net/mlx5: E-Switch, Assign a different position for uplink rep and vportBodong Wang
In offloads mode, the current implementation puts the uplink representor at index zero of the vport reps array. It is not "natural" to place it at index 0 since we want to put the representor for vport 0 at index 0 with the introduction of SmartNIC. A separate patch will handle the case whether a rep is needed for vport 0 (PF vport). So, we want to have a different placeholder for uplink vport and representor. It was placed at the end of vport and rep array. Since vport number can no longer act as an index into the vport or representors arrays, use functions to map vport numbers to indices when accessing the vports or representors arrays, and vice versa.

2019-02-15net/mlx5: E-Switch, Centralize repersentor reg/unreg to eswitch driverBodong Wang
Eswitch has two users: IB and ETH. They both register repersentors when mlx5 interface is added, and unregister the repersentors when mlx5 interface is removed. Ideally, each driver should only deal with the entities which are unique to itself. However, current IB and ETH drivers have to perform the following eswitch operations: 1. When registering, specify how many vports to register. This number is the same for both drivers which is the total available vport numbers. 2. When unregistering, specify the number of registered vports to do unregister. Also, unload the repersentors which are already loaded. It's unnecessary for eswitch driver to hands out the control of above operations to individual driver users, as they're not unique to each driver. Instead, such operations should be centralized to eswitch driver. This consolidates eswitch control flow, and simplified IB and ETH driver. This patch doesn't change any functionality.

In downstream patches with introducing of ECPF and UPLINK vports, it's not consecutive any more. Use getter to get specific vport/rep, and use iterator to traversal a list of vport/rep.

2019-02-15net/mlx5: E-Switch, Split VF and special vports for offloads modeBodong Wang
When driver is entering offloads mode, there are two major tasks to do: initialize flow steering and create representors. Flow steering should make sure enough flow table/group spaces are reserved for all reps. Representors will be created in a group, all or none. With the introduction of ECPF, flow steering should still reserve the same spaces. But, the representors are not always loaded/unloaded in a single piece. Once ECPF is in offloads mode, it will get the number of VF changing event from host PF. In such scenario, only the VF reps should be loaded/unloaded, not the reps for special vports (such as the uplink vport). Thus, when entering offloads mode, driver should specify the total number of reps, and the number of VF reps separately. When leaving offloads mode, the cleanup should use the information self-contained in eswitch such as number of VFs. This patch doesn't change any functionality.

When referring to another vport, put the vport number of the referred vport and put 1 in other_vport. It was assumed that driver is accessing other vport when vport number is greater than 0. With the above scheme, the case that ECPF eswitch manager is trying to access host PF vport will fall over with scheme 1 as the vport number is 0. This is apparently wrong as driver is trying to refer other vport. As such usage can only happen in the eswitch context, change relevant functions to provide other vport input properly.

2019-02-15net/mlx5: E-Switch, Properly refer to the esw manager vportBodong Wang
In SmartNIC mode, the eswitch manager is not necessarily the PF (vport 0). Use a helper function to get the correct eswitch manager vport number and cache on the eswitch instance for fast reference.

2019-02-15net/mlx5: Correctly set LAG mode for ECPFBodong Wang
When bonding is added, driver assumes that it's RoCE LAG if no VF is enabled. This is not enough for ECPF as the VF is enabled in host PF side. LAG should only choose RoCE mode when both slave devices meet conditions below: 1. E-Switch offloads mode is NONE. 2. No VF is enabled.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Merge mlx5-next shared branched into net-next, From Bodong Wang: 1) Introduction of ECPF (Embedded CPU Physical Function), and low level bits for mlx5 SmartNic capabilities support. 2) Vport enumeration refactoring that affect mlx5_ib and mlx5_core From Aya Levin, 3) Add support for 50Gbps per lane link modes in the Port Type and Speed register (PTYS) 4) Refactor low level query functions for PTYS register 5) Add support for 50Gbps per lane link modes to mlx5_ib Note: due to a change in API in mlx5/core and a later patch from net-next, a fixup was squashed with this merge commit that replaces FDB_UPLINK_VPORT with MLX5_VPORT_UPLINK which exists only in upstream net-next.

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.

2019-02-15net: bpf: remove XDP_QUERY_XSK_UMEM enumeratorJan Sokolowski
Commit c9b47cc1fabc ("xsk: fix bug when trying to use both copy and zero-copy on one queue id") moved the umem query code to the AF_XDP core, and therefore removed the need to query the netdevice for a umem. This patch removes XDP_QUERY_XSK_UMEM and all code that implement that behavior, which is just dead code.
