      htb: add support for direct_qlen attribute · b43f3318
      Eric Dumazet authored
      TCA_HTB_DIRECT_QLEN attribute is supported since linux-3.10
      
      HTB classes use an internal pfifo queue, which limit was not reported
      by tc, and value inherited from device tx_queue_len at setup time.
      
      With this patch, tc displays the value and can change it.

      tc: support TCA_STATS_RATE_EST64 · 8f7574ed
      Eric Dumazet authored
      Since linux-3.11, rate estimator can provide TCA_STATS_RATE_EST64
      when rate (bytes per second) is above 2^32 (~34 Mbits)
      
      Change tc to use this attribute for high rates.

      Stephen Hemminger authored
      New command line flag to output statistics in JSON format.
      In our envrionment, we have scripts that parse output of commands.
      It is better to use a format supported by existing parsers.

      linklayer interface between kernel and tc/userspace · 3e92ff52
      Jesper Dangaard Brouer authored
      This iproute2 tc patch is connected to the kernel
       - commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling)
      
      The rate table calculated by tc, have gotten replaced in the kernel
      and is no-longer used for lookups.
      
      This happened in kernel release v3.8 caused by kernel
       - commit 56b765b79 ("htb: improved accuracy at high rates").
      This change unfortunately caused breakage of tc overhead and
      linklayer parameters.
      
       Kernel overhead handling got fixed in kernel v3.10 by
       - commit 01cb71d2d47 (net_sched: restore "overhead xxx" handling)
      
       Kernel linklayer handling got fixed in kernel v3.11 by
       - commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling)
      
      The linklayer fix introduced a struct change, that allow the linklayer
      attribute to be transferred between tc and kernel. This patch make use
      of this linklayer attribute.
      
      The linklayer setting is transfer to the kernel.  And linklayer
      setting received from the kernel is printed with a prefixed
      "linklayer" when listing current configuration.  The default
      TC_LINKLAYER_ETHERNET is only printed in detailed output mode.

      ipnetns: fix ip batch mode when using 'netns exec' · 3c61c01a
      Nicolas Dichtel authored
      Since commit a05f6511, ip batch mode is broken when using 'netns exec' cmd.
      
      When WIFEXITED() returns true, it means that the child exited normally, hence
      we must not call exit() but just returns the status. If we call exit, the next
      commands in the file file are not executed.
      If WIFEXITED() returns false, we can call exit() because it means that the
      child failed.
      
      This patch partially reverts commit a05f6511.
