      e1000: call ndo_stop() instead of dev_close() when running offline selftest · 1f2f83f8
      Stefan Assmann authored
      
      
      Calling dev_close() causes IFF_UP to be cleared which will remove the
      interfaces routes and some addresses. That's probably not what the user
      intended when running the offline selftest. Besides this does not happen
      if the interface is brought down before the test, so the current
      behaviour is inconsistent.
      Instead call the net_device_ops ndo_stop function directly and avoid
      touching IFF_UP at all.

      ====================
      mlxsw: Introduce support for Data Center Bridging
      
      Ido says:
      
      This patchset introduces support for Quality of Service (QoS) as part of the
      IEEE Data Center Bridiging (DCB) standards.
      
      Patches 1-9 do the required device initialization. Specifically, patches 1-6
      initialize the ports' headroom buffers, which are used at ingress to store
      incoming packets while they go through the switch's pipeline. Patches 7-9
      complete them by initializing the egress scheduling.
      
      The pipeline mentioned above determines the packet's egress port(s) and
      traffic class. Ideally, once out of the pipeline the packet moves to the
      switch's shared buffer (to be introduced in Jiri's patchset, currently
      default values are used) and scheduled for transmission according to its
      traffic class. The egress scheduling is configured according to the 802.1Qaz
      standard, which is part of the DCB infrastructure supported by Linux. This
      is introduced in patches 10-12.
      
      Even after going through the pipeline packets are not always eligible to
      enter the shared buffer. This is determined by the amount of available space
      and the quotas associated with the packet. However, if flow control is
      enabled and the packet is associated with the lossless flow, then it will
      stay in the headroom and won't be discarded. This is introduced in patches
      13-17.
      
      Please check individual commit messages for more info, as I tried to keep
      them pretty detailed.
