      IB/mlx5: Fix RC transport send queue overhead computation · 75c1657e
      Leon Romanovsky authored
      Fix the RC QPs send queue overhead computation to take into account
      two additional segments in the WQE which are needed for registration
      operations.
      
      The ATOMIC and UMR segments can't coexist together, so chose maximum out
      of them.
      
      The commit 9e65dc37 ("IB/mlx5: Fix RC transport send queue overhead
      computation") was intended to update RC transport as commit messages
      states, but added the code to UC transport.

      IB/ipoib: fix for rare multicast join race condition · 08bc3276
      Alex Estrin authored
      A narrow window for race condition still exist between
      multicast join thread and *dev_flush workers.
      A kernel crash caused by prolong erratic link state changes
      was observed (most likely a faulty cabling):

      .....
       }
      Proposed patch should prevent multicast join task to continue
      if link state change is detected.

      Changes from v4:
      - as suggested by Doug Ledford, optimized spinlock usage,
      i.e. ipoib_mcast_join() is called with lock held.
      Changes from v3:
      - sync with priv->lock before flag check.
      Chages from v2:
      - Move check for OPER_UP flag state to mcast_join() to
      ensure no event worker is in progress.
      - minor style fixes.
      Changes from v1:
      - No need to lock again if error detected.
