+Subject: [PATCH] options: fix parsing of boolean attributes
+
+Boolean attributes were parsed the same way as string attributes,
+so a value of { "bool_attr": "true" } would be parsed correctly, but
+{ "bool_attr": true } (without quotes) was parsed as false.

+ *
+
+Usage of the library functions:
+
+  The main datastructure for a switch is the struct switch_device
+  To get started, you first need to use switch_connect() to probe
+  for switches and allocate an instance of this struct.
+
+  There are two possible usage modes:
+    dev = switch_connect("eth0");
+      - this call will look for a switch registered for the linux device
+  	  "eth0" and only allocate a switch_device for this particular switch.
+
+    dev = switch_connect(NULL)
+      - this will return one switch_device struct for each available
+  	  switch. The switch_device structs are chained with by ->next pointer
+
+  Then to query a switch for all available attributes, use:
+    swlib_scan(dev);
+
+  All allocated datastructures for the switch_device struct can be freed with
+    swlib_free(dev);
+  or
+    swlib_free_all(dev);
+
+  The latter traverses a whole chain of switch_device structs and frees them all
+
+  Switch attributes (struct switch_attr) are divided into three groups:
+    dev->ops:
+      - global settings
+    dev->port_ops:
+      - per-port settings
+    dev->vlan_ops:
+      - per-vlan settings
+
+  switch_lookup_attr() is a small helper function to locate attributes
+  by name.
+
+  switch_set_attr() and switch_get_attr() can alter or request the values
+  of attributes.
+
+Usage of the switch_attr struct:
+
+  ->atype: attribute group, one of:
+    - SWLIB_ATTR_GROUP_GLOBAL
+    - SWLIB_ATTR_GROUP_VLAN
+    - SWLIB_ATTR_GROUP_PORT
+
+  ->id: identifier for the attribute
+
+  ->type: data type, one of:
+    - SWITCH_TYPE_INT
+    - SWITCH_TYPE_STRING
+    - SWITCH_TYPE_PORT
+
+  ->name: short name of the attribute
+  ->description: longer description
+  ->next: pointer to the next attribute of the current group
+
+
+Usage of the switch_val struct:
+
+  When setting attributes, following members of the struct switch_val need
+  to be set up:
+
+    ->len (for attr->type == SWITCH_TYPE_PORT)
+    ->port_vlan:
+      - port number (for attr->atype == SWLIB_ATTR_GROUP_PORT), or:
+      - vlan number (for attr->atype == SWLIB_ATTR_GROUP_VLAN)
+    ->value.i (for attr->type == SWITCH_TYPE_INT)
+    ->value.s (for attr->type == SWITCH_TYPE_STRING)
+      - owned by the caller, not stored in the library internally
+    ->value.ports (for attr->type == SWITCH_TYPE_PORT)
+      - must point to an array of at lest val->len * sizeof(struct switch_port)
+
+  When getting string attributes, val->value.s must be freed by the caller
+  When getting port list attributes, an internal static buffer is used,
+  which changes from call to call.

+Subject: [PATCH 30/30] Fix entries in /etc/hosts disabling static leases.
+
+It is possible for a config entry to have one address family specified by a
+dhcp-host directive and the other added from /etc/hosts. This is especially
+common on OpenWrt because it uses odhcpd for DHCPv6 and IPv6 leases are
+imported into dnsmasq via a hosts file.
+
+To handle this case there need to be separate *_HOSTS flags for IPv4 and IPv6.
+Otherwise when the hosts file is reloaded it will clear the CONFIG_ADDR(6) flag
+which was set by the dhcp-host directive.
