   4 Subject: [PATCH] src/nl_extras.h: fix compatibility with libnl 3.3.0
   5
   6 nl_extras.h defines a set of nla_set_s*() functions if not provided by
   7 libnl. They are provided by libnl since version 3.2.26. The test
   8 (LIBNL_VER_MIC <= 26) was working fine while libnl was in the 3.2.x
   9 series, but now that they have incremented the minor version, the
  10 micro version was reset to 0, with the latest libnl version being
  11 3.3.0.
  12
  13 Due to this, the condition (LIBNL_VER_MIC <= 26) is true, and we get
  14 redefinition errors because nl_extras.h redefines functions already
  15 provided by libnl.
  16
  17 This commit improves the condition so that nl_extras.h provides the
  18 missing functions only if the minor version is < 2, or if minor is 2
  19 and micro is < 26.
