      i40e: fix handling of HW ATR eviction · 6964e53f
      Jacob Keller authored
      A recent commit to refactor the driver and remove the hw_disabled_flags
      field accidentally introduced two regressions. First, we overwrote
      pf->flags which removed various key flags including the MSI-X settings.
      
      Additionally, it was intended that we have now two flags,
      HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done,
      and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere.
      
      This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely
      updates pf->flags instead of overwriting it.
      
      Without this patch we will have many problems including disabling MSI-X
      support, and we'll attempt to use HW ATR eviction on devices which do
      not support it.

      When HSR interface is setup using ip link command, an annoying warning
      appears with the trace as below:-

      As this is an expected path to hsr_get_node() with frame coming from
      the master interface, add a check to ensure packet is not from the
      master port and then warn.

      proc: snmp6: Use correct type in memset · 3500cd73
      Christian Perle authored
      Reading /proc/net/snmp6 yields bogus values on 32 bit kernels.
      Use "u64" instead of "unsigned long" in sizeof().

      ====================
      pull-request: can 2017-06-09
      
      this is a pull request of 6 patches for net/master.
      
      There's a patch by Stephane Grosjean that fixes an uninitialized symbol warning
      in the peak_canfd driver. A patch by Johan Hovold to fix the product-id
      endianness in an error message in the the peak_usb driver. A patch by Oliver
      Hartkopp to enable CAN FD for virtual CAN devices by default. Three patches by
      me, one makes the helper function can_change_state() robust to be called with
      cf == NULL. The next patch fixes a memory leak in the gs_usb driver. And the
      last one fixes a lockdep splat by properly initialize the per-net
      can_rcvlists_lock spin_lock.
