Access to the IPv4 forwarding table, interfaces, and configuration.
This class defines the API to manipulate the following aspects of the IPv4 implementation:
Each NetDevice has conceptually a single Ipv4 interface associated with it (the corresponding structure in the Linux Ipv4 implementation is struct in_device). Each interface may have one or more Ipv4 addresses associated with it. Each Ipv4 address may have different subnet mask, scope, etc., so all of this per-address information is stored in an Ipv4InterfaceAddress class (the corresponding structure in Linux is struct in_ifaddr)
Ipv4 attributes such as whether IP forwarding is enabled and disabled are also stored in this class
TO DO: Add API to allow access to the Ipv4 neighbor table

Determine whether address and interface corresponding to received packet can be accepted for local delivery.
address | The IP address being considered |
iif | The incoming Ipv4 interface index |
This method can be used to determine whether a received packet has an acceptable address for local delivery on the host. The address may be a unicast, multicast, or broadcast address. This method will return true if address is an exact match of a unicast address on one of the host's interfaces (see below), if address corresponds to a multicast group that the host has joined (and the incoming device is acceptable), or if address corresponds to a broadcast address.
If the Ipv4 attribute StrongEndSystemModel is true, the address must match one assigned to the incoming device. If the attribute is false, the unicast address may match any of the Ipv4 addresses on any interface.

Return the first primary source address with scope less than or equal to the requested scope, to use in sending a packet to destination dst out of the specified device.
This method mirrors the behavior of Linux inet_select_addr() and is provided because interfaces may have multiple IP addresses configured on them with different scopes, and with a primary and secondary status. Secondary addresses are never returned.
If a non-zero device pointer is provided, the method first tries to return a primary address that is configured on that device, and whose subnet matches that of dst and whose scope is less than or equal to the requested scope. If a primary address does not match the subnet of dst but otherwise matches the scope, it is returned. If no such address on the device is found, the other devices are searched in order of their interface index, but not considering dst as a factor in the search. Because a loopback interface is typically the first one configured on a node, it will be the first alternate device to be tried. Addresses scoped at LINK scope are not returned in this phase.
If no device pointer is provided, the same logic as above applies, only that there is no preferred device that is consulted first. This means that if the device pointer is null, input parameter dst will be ignored.
If there are no possible addresses to return, a warning log message is issued and the all-zeroes address is returned.
