      Switchdev was a case of RTNH_H_{EXTERNAL --> OFFLOAD}
      renaming overlapping with net-next changes of various
      sorts.
      
      phy.c was a case of two changes, one adding a local
      variable to a function whilst the second was removing
      one.
      
      tcp.c overlapped a deadlock fix with the addition of new tcp_info
      statistic values.
      
      macb.c involved the addition of two zyncq device entries.
      
      skbuff.h involved adding back ipv4_daddr to nf_bridge_info
      whilst net-next changes put two other existing members of
      that struct into a union.

      ====================
      pktgen: cleanups and introducing new samples/pktgen scripts
      
      v3:
       - Aborted v2 send due it was not generating diff stat
         (this is a bug in stg-mail, if not in the root directory)
      
      v2: address nitpicks from Cong Wang
       - Remove useless cat's, but keep them for old pgset()
       - Comment on: Due to pgctrl, cannot use exit code $? from grep
       - Use arithmetic compare in pktgen_sample03_burst_single_flow.sh
      
      This patchset is focused on making pktgen easier to use and better
      documented. It contains a number of documentation updates and minor
      changes to pktgen.  The major contribution is introduction of common
      helper function for sample scripts.
      
      Instead of the old pgset() function, three new shell functions for
      configuring the different components of pktgen are introduced:
       pg_ctrl(), pg_thread() and pg_set().
      
      The new functions correspond to pktgens different components.
       * pg_ctrl()   control "pgctrl" (/proc/net/pktgen/pgctrl)
       * pg_thread() control the kernel threads and binding to devices
       * pg_set()    control setup of individual devices
      
      Helpers also provide consistent parameter parsing across the sample
      scripts.
      
      Usage example:
       ./pktgen_sample01_simple.sh -i eth41 -m 00:12:C0:02:AC:5A -d 192.168.41.2
      
      Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX
        -i : ($DEV)       output interface/device (required)
        -s : ($PKT_SIZE)  packet size
        -d : ($DEST_IP)   destination IP
        -m : ($DST_MAC)   destination MAC-addr
        -t : ($THREADS)   threads to start
        -c : ($SKB_CLONE) SKB clones send before alloc new SKB
        -b : ($BURST)     HW level bursting of SKBs
        -v : ($VERBOSE)   verbose
        -x : ($DEBUG)     debug
      
      These scripts are borrowed from:

      pktgen: add benchmark script pktgen_bench_xmit_mode_netif_receive.sh · 05a14d5e
      Jesper Dangaard Brouer authored
      This script pktgen_bench_xmit_mode_netif_receive.sh is a benchmark
      script, which can be used for benchmarking part of the network stack.
      This can be used for performance improving or catching regression in
      that area.
      
      The script is developed for benchmarking ingress qdisc path, original
      idea by Alexei Starovoitov.  This script don't really need any
      hardware.  This is achieved via the recently introduced stack inject
      feature "xmit_mode netif_receive". See commit 62f64aed ("pktgen:
      introduce xmit_mode '<start_xmit|netif_receive>'").
