Resets a network adapter and reinitializes it with the parameters that were

|
This function resets a network adapter and reinitializes it with the parameters
|
|
that were provided in the previous call to Initialize(). The transmit and
|
|
receive queues are emptied and all pending interrupts are cleared.
|
|
Receive filters, the station address, the statistics, and the multicast-IP-to-HW
|
|
MAC addresses are not reset by this call. If the network interface was
|
|
successfully reset, then EFI_SUCCESS will be returned. If the driver has not
|
|
been initialized, EFI_DEVICE_ERROR will be returned.
|
|
|
|
@param This A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
|
|
@param ExtendedVerification Indicates that the driver may perform a more
|
|
exhaustive verification operation of the device
|
|
during reset.
|
|
|
|
@retval EFI_SUCCESS The network interface was reset.
|
|
@retval EFI_NOT_STARTED The network interface has not been started.
|
|
@retval EFI_INVALID_PARAMETER One or more of the parameters has an unsupported value.

@retval EFI_DEVICE_ERROR The command could not be sent to the network interface.
