/**
This is the SNP interface routine for initializing the interface
This routine basically retrieves snp structure, checks the SNP state and
calls the pxe_initialize routine to actually do the undi initialization
Resets a network adapter and allocates the transmit and receive buffers
required by the network interface; optionally, also requests allocation of
additional transmit and receive buffers.
@param this context pointer
@param extra_rx_buffer_size optional parameter, indicates extra space for
rx_buffers
@param extra_tx_buffer_size optional parameter, indicates extra space for
tx_buffers
This function allocates the transmit and receive buffers required by the network
interface. If this allocation fails, then EFI_OUT_OF_RESOURCES is returned.
If the allocation succeeds and the network interface is successfully initialized,
then EFI_SUCCESS will be returned.
@param This A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
@param ExtraRxBufferSize The size, in bytes, of the extra receive buffer space
that the driver should allocate for the network interface.
Some network interfaces will not be able to use the
extra buffer, and the caller will not know if it is
actually being used.
@param ExtraTxBufferSize The size, in bytes, of the extra transmit buffer space
that the driver should allocate for the network interface.
Some network interfaces will not be able to use the
extra buffer, and the caller will not know if it is
actually being used.
@retval EFI_SUCCESS The network interface was initialized.
@retval EFI_NOT_STARTED The network interface has not been started.
@retval EFI_OUT_OF_RESOURCES There was not enough memory for the transmit and
receive buffers.
@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.
@retval EFI_UNSUPPORTED The increased buffer size feature is not supported.
