Until these parameters are initialized, no network traffic can be sent or

/**
Adds and deletes routing table entries.
The Routes() function adds a route to or deletes a route from the routing table.
Routes are determined by comparing the SubnetAddress with the destination IP
address and arithmetically AND-ing it with the SubnetMask. The gateway address
must be on the same subnet as the configured station address.
The default route is added with SubnetAddress and SubnetMask both set to 0.0.0.0.
The default route matches all destination IP addresses that do not match any
other routes.
A zero GatewayAddress is a nonroute. Packets are sent to the destination IP
address if it can be found in the Address Resolution Protocol (ARP) cache or
on the local subnet. One automatic nonroute entry will be inserted into the
routing table for outgoing packets that are addressed to a local subnet
(gateway address of 0.0.0.0).
Each instance of the EFI UDPv4 Protocol has its own independent routing table.
Instances of the EFI UDPv4 Protocol that use the default IP address will also
have copies of the routing table provided by the EFI_IP4_CONFIG_PROTOCOL. These
copies will be updated automatically whenever the IP driver reconfigures its
instances; as a result, the previous modification to these copies will be lost.
@param This The pointer to the EFI_UDP4_PROTOCOL instance.
@param DeleteRoute Set to TRUE to delete this route from the routing table.
Set to FALSE to add this route to the routing table.
@param SubnetAddress The destination network address that needs to be routed.
@param SubnetMask The subnet mask of SubnetAddress.
@param GatewayAddress The gateway IP address for this route.
@retval EFI_SUCCESS The operation completed successfully.

@retval EFI_INVALID_PARAMETER One or more parameters are invalid.
@retval EFI_OUT_OF_RESOURCES Could not add the entry to the routing table.
@retval EFI_NOT_FOUND This route is not in the routing table.

Polls for incoming data packets and processes outgoing data packets.
The Poll() function can be used by network drivers and applications to increase
the rate that data packets are moved between the communications device and the
transmit and receive queues.
In some systems, the periodic timer event in the managed network driver may not
poll the underlying communications device fast enough to transmit and/or receive
all data packets without missing incoming packets or dropping outgoing packets.
Drivers and applications that are experiencing packet loss should try calling
the Poll() function more often.

driver updates the Token.Status and Token.Packet.RxData fields and the Token.Event
