/**
Used to perform TFTP and MTFTP services.
This function is used to perform TFTP and MTFTP services. This includes the
TFTP operations to get the size of a file, read a directory, read a file, and
write a file. It also includes the MTFTP operations to get the size of a file,
read a directory, and read a file. The type of operation is specified by Operation.
If the callback function that is invoked during the TFTP/MTFTP operation does
not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will
be returned.
For read operations, the return data will be placed in the buffer specified by
BufferPtr. If BufferSize is too small to contain the entire downloaded file,
then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero
or the size of the requested file (the size of the requested file is only returned
if the TFTP server supports TFTP options). If BufferSize is large enough for the
read operation, then BufferSize will be set to the size of the downloaded file,
and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services
should use the get-file-size operations to determine the size of the downloaded
file prior to using the read-file operations--especially when downloading large
(greater than 64 MB) files--instead of making two calls to the read-file operation.
Following this recommendation will save time if the file is larger than expected
and the TFTP server does not support TFTP option extensions. Without TFTP option
extension support, the client has to download the entire file, counting and discarding
the received packets, to determine the file size.
For write operations, the data to be sent is in the buffer specified by BufferPtr.
BufferSize specifies the number of bytes to send. If the write operation completes
successfully, then EFI_SUCCESS will be returned.
For TFTP "get file size" operations, the size of the requested file or directory
is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server
does not support options, the file will be downloaded into a bit bucket and the
length of the downloaded file will be returned. For MTFTP "get file size" operations,
if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED
will be returned.
This function can take up to 10 seconds to timeout and return control to the caller.
If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.
If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,
then the TFTP sequence is stopped and EFI_ABORTED will be returned.
The format of the data returned from a TFTP read directory operation is a null-terminated
filename followed by a null-terminated information string, of the form
"size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f - note that
the seconds field can be a decimal number), where the date and time are UTC. For
an MTFTP read directory command, there is additionally a null-terminated multicast
IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The final
entry is itself null-terminated, so that the final information string is terminated
with two null octets.
@param This The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance.
@param Operation The type of operation to perform.
@param BufferPtr A pointer to the data buffer.
@param Overwrite Only used on write file operations. TRUE if a file on a remote server can
be overwritten.
@param BufferSize For get-file-size operations, *BufferSize returns the size of the
requested file.
@param BlockSize The requested block size to be used during a TFTP transfer.
@param ServerIp The TFTP / MTFTP server IP address.
@param Filename A Null-terminated ASCII string that specifies a directory name or a file
name.
@param Info The pointer to the MTFTP information.
@param DontUseBuffer Set to FALSE for normal TFTP and MTFTP read file operation.
@retval EFI_SUCCESS The TFTP/MTFTP operation was completed.
@retval EFI_NOT_STARTED The PXE Base Code Protocol is in the stopped state.
@retval EFI_INVALID_PARAMETER One or more parameters are invalid.
@retval EFI_DEVICE_ERROR The network device encountered an error during this operation.
@retval EFI_BUFFER_TOO_SMALL The buffer is not large enough to complete the read operation.
@retval EFI_ABORTED The callback function aborted the TFTP/MTFTP operation.
@retval EFI_TIMEOUT The TFTP/MTFTP operation timed out.

/**
Updates the IP receive filters of a network device and enables software filtering.
The NewFilter field is used to modify the network device's current IP receive
filter settings and to enable a software filter. This function updates the IpFilter
field of the EFI_PXE_BASE_CODE_MODE structure with the contents of NewIpFilter.
The software filter is used when the USE_FILTER in OpFlags is set to UdpRead().
The current hardware filter remains in effect no matter what the settings of OpFlags
are, so that the meaning of ANY_DEST_IP set in OpFlags to UdpRead() is from those
packets whose reception is enabled in hardware - physical NIC address (unicast),
broadcast address, logical address or addresses (multicast), or all (promiscuous).
UdpRead() does not modify the IP filter settings.
Dhcp(), Discover(), and Mtftp() set the IP filter, and return with the IP receive
filter list emptied and the filter set to EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP.
If an application or driver wishes to preserve the IP receive filter settings,
it will have to preserve the IP receive filter settings before these calls, and
use SetIpFilter() to restore them after the calls. If incompatible filtering is
requested (for example, PROMISCUOUS with anything else), or if the device does not
support a requested filter setting and it cannot be accommodated in software
(for example, PROMISCUOUS not supported), EFI_INVALID_PARAMETER will be returned.
The IPlist field is used to enable IPs other than the StationIP. They may be
multicast or unicast. If IPcnt is set as well as EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP,
then both the StationIP and the IPs from the IPlist will be used.
@param This The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance.
@param NewFilter The pointer to the new set of IP receive filters.
@retval EFI_SUCCESS The IP receive filter settings were updated.

Uses the ARP protocol to resolve a MAC address.
This function uses the ARP protocol to resolve a MAC address. The UsingIpv6 field
of the EFI_PXE_BASE_CODE_MODE structure is used to determine if IPv4 or IPv6
addresses are being used. The IP address specified by IpAddr is used to resolve
a MAC address. If the ARP protocol succeeds in resolving the specified address,
then the ArpCacheEntries and ArpCache fields of the EFI_PXE_BASE_CODE_MODE structure
are updated, and EFI_SUCCESS is returned. If MacAddr is not NULL, the resolved
MAC address is placed there as well.
If the PXE Base Code protocol is in the stopped state, then EFI_NOT_STARTED is
returned. If the ARP protocol encounters a timeout condition while attempting
to resolve an address, then EFI_TIMEOUT is returned. If the Callback Protocol
does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED is
returned.

Updates the parameters that affect the operation of the PXE Base Code Protocol.
This function sets parameters that affect the operation of the PXE Base Code Protocol.
The parameter specified by NewAutoArp is used to control the generation of ARP
protocol packets. If NewAutoArp is TRUE, then ARP Protocol packets will be generated
as required by the PXE Base Code Protocol. If NewAutoArp is FALSE, then no ARP
Protocol packets will be generated. In this case, the only mappings that are
available are those stored in the ArpCache of the EFI_PXE_BASE_CODE_MODE structure.

service, then the service will fail. This function updates the AutoArp field of
the EFI_PXE_BASE_CODE_MODE structure to NewAutoArp.
