92 Sets or clears the operational parameters for the MNP child driver.
94 The Configure() function is used to set, change, or reset the operational
95 parameters for the MNP child driver instance. Until the operational parameters
96 have been set, no network traffic can be sent or received by this MNP child
97 driver instance. Once the operational parameters have been reset, no more
98 traffic can be sent or received until the operational parameters have been set
100 Each MNP child driver instance can be started and stopped independently of
101 each other by setting or resetting their receive filter settings with the
102 Configure() function.
103 After any successful call to Configure(), the MNP child driver instance is
104 started. The internal periodic timer (if supported) is enabled. Data can be
105 transmitted and may be received if the receive filters have also been enabled.
106 Note: If multiple MNP child driver instances will receive the same packet
107 because of overlapping receive filter settings, then the first MNP child
108 driver instance will receive the original packet and additional instances will
109 receive copies of the original packet.
110 Note: Warning: Receive filter settings that overlap will consume extra
111 processor and/or DMA resources and degrade system and network performance.

454 Places asynchronous outgoing data packets into the transmit queue.

459 completion token, and these fields cannot be NULL. When the transmit operation
460 completes, the MNP updates the Token.Status field and the Token.Event is
