      Intel Wired LAN Driver Fixes 2019-11-08
      This series contains fixes to igb, igc, ixgbe, i40e, iavf and ice
      Colin Ian King fixes a potentially wrap-around counter in a for-loop.
      Nick fixes the default ITR values for the iavf driver to 50 usecs
      Arkadiusz fixes 'ethtool -m' for X722 devices where the correct value
      cannot be obtained from the firmware, so add X722 to the check to ensure
      the wrong value is not returned.
      Jake fixes igb and igc drivers in their implementation of launch time
      support by declaring skb->tstamp value as ktime_t instead of s64.
      Magnus fixes ixgbe and i40e where the need_wakeup flag for transmit may
      not be set for AF_XDP sockets that are only used to send packets.

      ixgbe: need_wakeup flag might not be set for Tx · 0843aa8f
      Magnus Karlsson authored
      The need_wakeup flag for Tx might not be set for AF_XDP sockets that
      are only used to send packets. This happens if there is at least one
      outstanding packet that has not been completed by the hardware and we
      get that corresponding completion (which will not generate an
      interrupt since interrupts are disabled in the napi poll loop) between
      the time we stopped processing the Tx completions and interrupts are
      enabled again. In this case, the need_wakeup flag will have been
      cleared at the end of the Tx completion processing as we believe we
      will get an interrupt from the outstanding completion at a later point
      in time. But if this completion interrupt occurs before interrupts
      are enable, we lose it and should at that point really have set the
      need_wakeup flag since there are no more outstanding completions that
      can generate an interrupt to continue the processing. When this
      happens, user space will see a Tx queue need_wakeup of 0 and skip
      issuing a syscall, which means will never get into the Tx processing
      again and we have a deadlock.
      This patch introduces a quick fix for this issue by just setting the
      need_wakeup flag for Tx to 1 all the time. I am working on a proper
      fix for this that will toggle the flag appropriately, but it is more
      challenging than I anticipated and I am afraid that this patch will
      not be completed before the merge window closes, therefore this easier
      fix for now. This fix has a negative performance impact in the range
      of 0% to 4%. Towards the higher end of the scale if you have driver
      and application on the same core and issue a lot of packets, and
      towards no negative impact if you use two cores, lower transmission
      speeds and/or a workload that also receives packets.
