+Subject: [PATCH 1/1] Fix regression in s_config_in_context() method
+
+Prior to commit 137286e9baecf6a3ba97722ef1b49c851b531810
+a config would not be considered in context if:
+a) it has no address family flags set
+b) it has the address family flag of current context set
+
+Since above commit config is considered in context if the
+address family is the opposite of current context.
+
+The result is that a config with two dhcp-host records,
+one for IPv6 and another for IPv4 no longer works, for
+example with the below config the config with the IPv6
+address would be considered in context for a DHCP(v4)
+request.
+ dhcp-host=52:54:00:bc:c3:fd,172.20.0.11,host2
+ dhcp-host=52:54:00:bc:c3:fd,[fd12:3456:789a:1::aadd],host2
+
+This commit restores the previous behavior.
