      RDMA/cxgb4: Fix bug for active and passive LE hash collision path · 793dad94
      Vipul Pandya 提交于
      Retries active opens for INUSE errors.
      
      Logs any active ofld_connect_wr error replies.
      
      Sends ofld_connect_wr on same ctrlq. It needs to go  on the same control txq as
      regular CPL active/passive messages.
      
      Retries on active open replies with EADDRINUSE.
      
      Uses active open fw wr only if active filter region is set.
      
      Adds stat for ofld_connect_wr failures.
      
      This patch also adds debugfs file to show endpoints.

      cxgb4: Add LE hash collision bug fix path in LLD driver · dca4faeb
      Vipul Pandya 提交于
      It supports establishing passive open connection through firmware filter work
      request. Passive open connection will go through this path as now instead of
      listening server we create a server filter which will redirect the incoming SYN
      packet to the offload queue.
      
      It divides filter region into regular filters and server filter portion. It
      introduces new server filter region which will be exclusively used for creating
      server filters. This region will not overlap with regular filter region.
      
      It provides new API cxgb4_alloc_sftid in LLD for getting stid in case of LE
      hash collision path. This new stid will be used to open server filter in the
      filter region.

      cxgb4: Add T4 filter support · f2b7e78d
      Vipul Pandya 提交于
      The T4 architecture is capable of filtering ingress packets at line rate
      using the rule in TCAM. If packet hits a rule in the TCAM then it can be either
      dropped or passed to the receive queues based on a rule settings.
      
      This patch adds framework for managing filters and to use T4's filter
      capabilities. It constructs a Firmware Filter Work Request which writes the
      filter at a specified index to get the work done. It hosts shadow copy of
      ingress filter entry to check field size limitations and save memory in the
      case where the filter table is large.
