# PATCH-FIX-OPENSUSE 0001-enic-fix-Type-punning-and-strict-aliasing-warning.patch
# This patch was originally taken from the fedora package but they have
# removed it since then because of
# http://osdir.com/ml/scm-fedora-commits/2016-03/msg00849.html
# However, the problem still exists and the fix has to find its way to the
# upstream code.
