/**
This is the SNP interface routine for getting the status
This routine basically retrieves snp structure, checks the SNP state and
calls the pxe_getstatus routine to actually get the undi status
Reads the current interrupt status and recycled transmit buffer status from a
network interface.
This function gets the current interrupt and recycled transmit buffer status
from the network interface. The interrupt status is returned as a bit mask in
InterruptStatus. If InterruptStatus is NULL, the interrupt status will not be
read. If TxBuf is not NULL, a recycled transmit buffer address will be retrieved.
If a recycled transmit buffer address is returned in TxBuf, then the buffer has
been successfully transmitted, and the status for that buffer is cleared. If
the status of the network interface is successfully collected, EFI_SUCCESS
will be returned. If the driver has not been initialized, EFI_DEVICE_ERROR will
be returned.
@param this context pointer
@param InterruptStatusPtr a non null pointer gets the interrupt status
@param TransmitBufferListPtrs a non null ointer gets the list of pointers of
previously transmitted buffers whose
transmission was completed asynchrnously.
@param This A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
@param InterruptStatus A pointer to the bit mask of the currently active
interrupts (see "Related Definitions"). If this is NULL,
the interrupt status will not be read from the device.
If this is not NULL, the interrupt status will be read
from the device. When the interrupt status is read, it
will also be cleared. Clearing the transmit interrupt does
not empty the recycled transmit buffer array.
@param TxBuf Recycled transmit buffer address. The network interface
will not transmit if its internal recycled transmit
buffer array is full. Reading the transmit buffer does
not clear the transmit interrupt. If this is NULL, then
the transmit buffer status will not be read. If there
are no transmit buffers to recycle and TxBuf is not NULL,
TxBuf will be set to NULL.
@retval EFI_SUCCESS The status of the network interface was retrieved.
@retval EFI_NOT_STARTED The network interface has not been started.
@retval EFI_INVALID_PARAMETER This parameter was NULL or did not point to a valid
EFI_SIMPLE_NETWORK_PROTOCOL structure.
@retval EFI_DEVICE_ERROR The command could not be sent to the network
interface.
