Hi Dave and Doug,
This series contains several low level and API updates for mlx5 core
driver to be shared as base code for net-next and rdma mlx5 4.9 submissions.
>From Saeed, ten patches that refactors old layouts of firmware commands which
were manually generated before we introduced the mlx5_ifc, now all of the firmware
commands inbox/outbox layouts moved to use mlx5_ifc and we remove the old
manually generated structures. Plus to those ten patches, we add two patches
that unifies mlx5 commands execution interface and improve the driver log messages
in that area.
>From Hadar and Ilya, added the needed hardware bits and infrastructure for
minimum inline headers setting and encap/decap commands and capabilities,
needed for E-Switch offloads.
>From Alex and Artemy, Update mlx5_ifc for modify RQ and XRC bits.
>From Noa, Expose mlx5 link modes so they can be used in RDMA tree for rdma tools.
>From Aviv, LAG support needed for RDMA.
- Add needed hardware structures, layouts and interface
- mlx5 core driver LAG implementation
- Introduce mlx5 core driver LAG API for mlx5_ib
>From Maor, add two low level patches for mlx5 hardware sniffer QP
infrastructure bits and capabilities, plus added the name space for sniffer
steering tables. Needed for RDMA subtree.
This series applies on top latest net-next and rdma/master, and smoothly merges with
the latest "Mellanox 100G mlx5 fixes 2016-08-16" series already applied into net branch.

Miller, Doug Ledford Cc: netdev, linux-rdma, Leon Romanovsky, Tal Alon, Matan Barak, Saeed Mahameed, Leon Romanovsky Prior to this patch we assumed that modify QP commands have the same layout. In ConnectX-4 for each QP transition there is a specific command and their layout can vary. e.g: 2err/2rst commands don't have QP context in their layout and before this patch we posted the QP context in those commands. Fortunately the FW only checks the suffix of the commands and executes them, while ignoring all invalid data sent after the valid command layout. This patch removes mlx5_modify_qp_mbox_in and changes mlx5_core_qp_modify to receive the required transition and QP context with opt_param_mask if needed. This way the caller is not required to provide the command inbox layout and it will be generated automatically. mlx5_core_qp_modify will generate the command inbox/outbox layouts according to the requested transition and will fill the requested parameters.

Miller, Doug Ledford Cc: netdev, linux-rdma, Leon Romanovsky, Tal Alon, Matan Barak, Saeed Mahameed, Leon Romanovsky Now as all commands use mlx5 ifc interface, instead of doing two calls for executing a command we embed command status checking into mlx5_cmd_exec to simplify the interface. Also we do here some cleanup for redundant software structures (inbox/outbox) and functions and improved command failure output.

Allows to set tx_affinity (tx port) for QPs and TISes. Allows to port remap QPs and TISes, overriding their tx_affinity behavior. - MODIFY_LAG Remap QPs and TISes to another port. - QUERY_LAG Query whether LAG mode is active. - DESTROY_LAG HW exits LAG mode, returning to non-LAG behavior. - CREATE_VPORT_LAG Merge Ethernet flow steering, such that traffic received on port two jumps to PF0 root flow table. Available only in LAG mode. - DESTROY_VPORT_LAG Ethernet flow steering returns to non-LAG behavior. Caps added: - lag_master Driver is in charge of managing the LAG. This is currently the only option. - num_lag_ports LAG is supported only if this field's value is 2. Other fields: - QP/TIS tx port affinity During LAG, this field controls on which port a QP or TIS resides. - TIS strict tx affinity When this field is set, the TIS will not be subject to port remap by CREATE_LAG/MODIFY_LAG. - LAG demux flow table Flow table used for redirecting non user-space traffic back to PF1 root flow table, if the packet was received on port two.

Miller, Doug Ledford Cc: netdev, linux-rdma, Leon Romanovsky, Tal Alon, Matan Barak, Aviv Heller, Saeed Mahameed, Leon Romanovsky From: Aviv Heller <avivh@mellanox.com> Available on dual port cards only, this feature keeps track, using netdev LAG events, of the bonding and link status of each port's PF netdev. When both of the card's PF netdevs are enslaved to the same bond/team master, and only them, LAG state is active. During LAG, only one IB device is present for both ports. In addition to the above, this commit includes FW commands used for managing the LAG, new facilities for adding and removing a single device by interface, and port remap functionality according to bond events. Please note that this feature is currently used only for mimicking Ethernet bonding for RoCE - netdevs functionality is not altered, and their bonding continues to be managed solely by bond/team driver.
