      net/mlx5: Introduce set delay drop command · c1e0bfc1
      Maor Gottlieb authored
      Add support to SET_DELAY_DROP command.
      
      This command will be used in downstream patches for delay packet drop.
      The timeout value should be indicated by delay_drop_timeout field.
      Packet processing will be delayed till timeout value passed or until
      more WQEs are posted.
      
      Setting this value to 0 disables the feature.

      IB/core: Introduce delay drop for a WQ · 7d9336d8
      Maor Gottlieb authored
      Work queue which is created with IB_WQ_FLAGS_DELAY_DROP won't
      cause packet drops when there aren't receive WQEs, but will wait until
      posting of receive WQEs or for some period of time that the device
      was configured with.
      
      It includes:
       * Add a new creation flag to enable delay drop functionality in a WQ.
       * A new capability was introduced - IB_RAW_PACKET_CAP_DELAY_DROP, which
         is the device's ability to delay packet drops when there aren't receive
         WQEs.

      IB/mlx5: Restore IB guid/policy for virtual functions · 7ecf6d8f
      Bodong Wang authored
      When a user sets port_guid, node_guid or policy of an IB virtual
      function, save this information in "struct mlx5_vf_context".
      
      This information will be restored later when pci_resume is called.
      To make sure this works, one can use aer-inject to generate PCI
      errors on mlx5 devices and verify if relevant fields are restored
      after PCI resume.

      IB/mlx5: Change logic for dispatching IB events for port state · fd65f1b8
      Moni Shoua authored
      The old logic ignored link state. This led to missing IB events like
      when link goes down on the switch while admin state is up or to redundant
      events like when admin state goes up while link is down.
      To fix that, probe the port state on NETDEV events and compare to last
      known state to decide if IB events needs to be dispatched.

      IB/mlx5: Add raw ethernet local loopback support · c85023e1
      Huy Nguyen authored
      Currently, unicast/multicast loopback raw ethernet
      (non-RDMA) packets are sent back to the vport.
      A unicast loopback packet is the packet with destination
      MAC address the same as the source MAC address.
      For multicast, the destination MAC address is in the
      vport's multicast filter list.
      
      Moreover, the local loopback is not needed if
      there is one or none user space context.
      
      After this patch, the raw ethernet unicast and multicast
      local loopback are disabled by default. When there is more
      than one user space context, the local loopback is enabled.
      
      Note that when local loopback is disabled, raw ethernet
      packets are not looped back to the vport and are forwarded
      to the next routing level (eswitch, or multihost switch,
      or out to the wire depending on the configuration).

       "As per my previous pull request, there were two drivers that each had
        a rather large number of legitimate fixes still to be sent.
      
        As it turned out, I also missed a reasonably large set of fixes from
        one person across the stack that are all important fixes. All in all,
        the bnxt_re, i40iw, and Dan Carpenter are 3/4 to 2/3rds of this pull
        request.
      
        There were some other random fixes that I didn't send in the last pull
        request that I added to this one. This catches the rdma stack up to
        the fixes from up to about the beginning of this week. Any more fixes
        I'll wait and batch up later in the -rc cycle. This will give us a
        good base to start with for basing a for-next branch on -rc2.
      
        Summary:
      
         - i40iw fixes

      When mapping a directory, we want the MAY_WRITE permissions to reflect
      whether or not we have permission to modify, add and delete the directory
      entries. MAY_EXEC must map to lookup permissions.
      
      On the other hand, for files, we want MAY_WRITE to reflect a permission
      to modify and extend the file.
