1. Changeset: d99061f1167c

Synopsis:
--------
- deconflict NetDevice::ifIndex and Ipv4::ifIndex (bug 85)

Changed public API (src/node)
--------

All function parameters named "ifIndex" that refer to an Ipv4 interface
are instead named "interface". 

- static const uint32_t Ipv4RoutingProtocol::IF_INDEX_ANY = 0xffffffff;
+ static const uint32_t Ipv4RoutingProtocol::INTERFACE_ANY = 0xffffffff;

- bool Ipv4RoutingProtocol::RequestIfIndex (Ipv4Address destination, uint32_t& ifIndex);
+ bool Ipv4RoutingProtocol::RequestInterface (Ipv4Address destination, uint32_t& interface);
(N.B. this particular function will be later renamed to RouteOutput() in the 
proposed IPv4 routing refactoring)

- uint32_t Ipv4::GetIfIndexByAddress (Ipv4Address addr, Ipv4Mask mask);
+ int_32t Ipv4::GetInterfaceForAddress (Ipv4Address address, Ipv4Mask mask) const;

- bool Ipv4::GetIfIndexForDestination (Ipv4Address dest, uint32_t &ifIndex) const;
+ bool Ipv4::GetInterfaceForDestination (Ipv4Address dest, uint32_t &interface) const;
(N.B. this function is not needed in the proposed Ipv4 routing refactoring)


New public API or classes (src/node)
--------

None.

Changed private API (src/internet-node)
--------

(similar API changes to the IPv4 implementation classes instantiating
the above public API) 

New private API or classes (src/internet-node)
--------

None.

2.  Changeset: e493e80274bd (implementation added in parallel)
    Changeset: TBD          (cut over of client code, remove old code)

Synopsis:
--------
- allow multiple IPv4 addresses to be assigned to an interface (bug 188)

Changed public API:
--------

We now have a new class and methods to account for the possibility of having
multiple IP addresses on an interface:

+  virtual uint32_t AddAddress (uint32_t interface, Ipv4InterfaceAddress address) = 0;
+  virtual Ipv4InterfaceAddress GetAddress (uint32_t interface, uint32_t addressIndex) const = 0;
+  virtual uint32_t GetNAddresses (uint32_t interface) const = 0;

This convenience function was removed:
-  virtual uint32_t GetIfIndexByAddress (Ipv4Address addr,
-    Ipv4Mask mask = Ipv4Mask("255.255.255.255"));

A few public methods were renamed because they were poorly named:
-  virtual uint32_t FindInterfaceForAddr (Ipv4Address addr,
+  virtual int32_t GetInterfaceForAddress (Ipv4Address address,
     Ipv4Mask mask) const = 0;
-  virtual int32_t FindInterfaceForDevice(Ptr<NetDevice> nd) const = 0;
+  virtual int32_t GetInterfaceForDevice (Ptr<const NetDevice> device) const = 0;


New public API or classes (src/node)
--------

class Ipv4InterfaceAddress:  This is a new class to parallel Linux 
struct in_ifaddr.  It holds IP addressing information, including mask, 
broadcast address, scope, whether primary or secondary, etc.

3.  Changeset: TBD

Synopsis:
--------
- Remove class Ipv4Impl from src/internet-stack

Changed public API:
--------

None

Changed private API
---------

Remove class Ipv4Impl; class Ipv4L3Protocol now inherits from class Ipv4
allow multiple IPv4 addresses to be assigned to an interface (bug 188)
