Subject: build: fix missing symbol for old kernel headers (#3530)
X-Git-Tag: v231.3~98
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=478418f9b414f837c9b30e9b1dcc5eaef079afd1

build: fix missing symbol for old kernel headers (#3530)

Fix issue where IN6_ADDR_GEN_MODE_STABLE_PRIVACY is undefined but
IFLA_INET6_ADDR_GEN_MODE is defined and thus the former does not get
fixed in missing.h. This occurs with kernel headers new enough to have
the IFLA_INET6_ADDR_GEN_MODE but old enough to not yet have
IN6_ADDR_GEN_MODE_STABLE_PRIVACY (e.g. 3.18).
