      net/sched: add skbprio scheduler · aea5f654
      Nishanth Devarajan authored
      Skbprio (SKB Priority Queue) is a queueing discipline that prioritizes packets
      according to their skb->priority field. Under congestion, already-enqueued lower
      priority packets will be dropped to make space available for higher priority
      packets. Skbprio was conceived as a solution for denial-of-service defenses that
      need to route packets with different priorities as a means to overcome DoS
      attacks.
      
      v5
      *Do not reference qdisc_dev(sch)->tx_queue_len for setting limit. Instead set
      default sch->limit to 64.
      
      v4
      *Drop Documentation/networking/sch_skbprio.txt doc file to move it to tc man
      page for Skbprio, in iproute2.
      
      v3
      *Drop max_limit parameter in struct skbprio_sched_data and instead use
      sch->limit.
      
      *Reference qdisc_dev(sch)->tx_queue_len only once, during initialisation for
      qdisc (previously being referenced every time qdisc changes).
      
      *Move qdisc's detailed description from in-code to Documentation/networking.
      
      *When qdisc is saturated, enqueue incoming packet first before dequeueing
      lowest priority packet in queue - improves usage of call stack registers.
      
      *Introduce and use overlimit stat to keep track of number of dropped packets.
      
      v2
      *Use skb->priority field rather than DS field. Rename queueing discipline as
      SKB Priority Queue (previously Gatekeeper Priority Queue).
      
      *Queueing discipline is made classful to expose Skbprio's internal priority
      queues.

      net: phy: add GBit master / slave error detection · b8f8c8eb
      Heiner Kallweit authored
      Certain PHY's have issues when operating in GBit slave mode and can
      be forced to master mode. Examples are RTL8211C, also the Micrel PHY
      driver has a DT setting to force master mode.
      If two such chips are link partners the autonegotiation will fail.
      Standard defines a self-clearing on read, latched-high bit to
      indicate this error. Check this bit to inform the user.

      ====================
      net whitespace cleanups
      
      Ran script that I use to check for trailing whitespace and
      blank lines at end of files across all files in net/ directory.
      These are errors that checkpatch reports and git flags.
      
      These are the resulting fixes broken up mostly by subsystem.
