      Jiri Pirko 提交于
      On some hw, link is not up during adding iface to team. That causes event
      not being sent to userspace and that may cause confusion.
      Fix this bug by sending port changed event once it's added to team.

      net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 · 42d94dcb
      Bjørn Mork 提交于
      One of the modes of Huawei E367 has this QMI/wwan interface:
      
       I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none)
       E:  Ad=83(I) Atr=03(Int.) MxPS=  64 Ivl=2ms
       E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
       E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms
      
      Huawei use subclass and protocol to identify vendor specific
      functions, so adding a new vendor rule for this combination.
      
      The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use
      the same subclass to identify the QMI/wwan function.  Replace the
      existing device specific UML290 entries with generic vendor matching,
      adding support for the Pantech P4200.
      
      The ZTE MF683 has 6 vendor specific interfaces, all using
      ff/ff/ff for cls/sub/prot.  Adding a match on interface #5 which
      is a QMI/wwan interface.

      This change makes it so that the VF can support the PF/VF API negotiation
      protocol.  Specifically in this case we are adding support for API 1.0
      which will mean that the VF is capable of cleaning up buffers that span
      multiple descriptors without triggering an error.

      igb: Remove artificial restriction on RQDPC stat reading · ae1c07a6
      Alexander Duyck 提交于
      For some reason the reading of the RQDPC register was being artificially
      limited to 4K.  Instead of limiting the value we should read the value and
      add the full amount.  Otherwise this can lead to a misleading number of
      dropped packets when the actual value is in fact much higher.

      r8169: use unlimited DMA burst for TX · aee77e4a
      Michal Schmidt 提交于
      The r8169 driver currently limits the DMA burst for TX to 1024 bytes. I have
      a box where this prevents the interface from using the gigabit line to its full
      potential. This patch solves the problem by setting TX_DMA_BURST to unlimited.
      
      The box has an ASRock B75M motherboard with on-board RTL8168evl/8111evl
      (XID 0c900880). TSO is enabled.
      
      I used netperf (TCP_STREAM test) to measure the dependency of TX throughput
      on MTU. I did it for three different values of TX_DMA_BURST ('5'=512, '6'=1024,
      '7'=unlimited). This chart shows the results:
      http://michich.fedorapeople.org/r8169/r8169-effects-of-TX_DMA_BURST.png
      
      Interesting points:
       - With the current DMA burst limit (1024):
         - at the default MTU=1500 I get only 842 Mbit/s.
         - when going from small MTU, the performance rises monotonically with
           increasing MTU only up to a peak at MTU=1076 (908 MBit/s). Then there's
           a sudden drop to 762 MBit/s from which the throughput rises monotonically
           again with further MTU increases.
       - With a smaller DMA burst limit (512):
         - there's a similar peak at MTU=1076 and another one at MTU=564.
       - With unlimited DMA burst:
         - at the default MTU=1500 I get nice 940 Mbit/s.
         - the throughput rises monotonically with increasing MTU with no strange
           peaks.
      
      Notice that the peaks occur at MTU sizes that are multiples of the DMA burst
      limit plus 52. Why 52? Because:
        20 (IP header) + 20 (TCP header) + 12 (TCP options) = 52
      
      The Realtek-provided r8168 driver (v8.032.00) uses unlimited TX DMA burst too,
      except for CFG_METHOD_1 where the TX DMA burst is set to 512 bytes.
      CFG_METHOD_1 appears to be the oldest MAC version of "RTL8168B/8111B",
      i.e. RTL_GIGA_MAC_VER_11 in r8169. Not sure if this MAC version really needs
      the smaller burst limit, or if any other versions have similar requirements.
