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