This is the language of the driver name that that the caller
is requesting, and it must match one of the languages specified
in SupportedLanguages. The number of languages supported by a
driver is up to the driver writer.

specified by Language.
Returns:
EFI_SUCCESS - The Unicode string for the Driver specified by This
and the language specified by Language was returned
in DriverName.

Routine Description:
Retrieves a Unicode string that is the user readable name of the controller
that is being managed by an EFI Driver.
Arguments:
This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
ControllerHandle - The handle of a controller that the driver specified by
This is managing. This handle specifies the controller
whose name is to be returned.
ChildHandle - The handle of the child controller to retrieve the name
of. This is an optional parameter that may be NULL. It
will be NULL for device drivers. It will also be NULL
for a bus drivers that wish to retrieve the name of the
bus controller. It will not be NULL for a bus driver
that wishes to retrieve the name of a child controller.
Language - A pointer to a three character ISO 639-2 language
identifier. This is the language of the controller name
that that the caller is requesting, and it must match one
of the languages specified in SupportedLanguages. The
number of languages supported by a driver is up to the

ControllerName - A pointer to the Unicode string to return. This Unicode
string is the name of the controller specified by
ControllerHandle and ChildHandle in the language specified
by Language from the point of view of the driver specified
by This.
Returns:
EFI_SUCCESS - The Unicode string for the user readable name in the
language specified by Language for the driver
specified by This was returned in DriverName.

EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.

Routine Description:
This is a callback routine supplied to UNDI at undi_start time.
UNDI call this routine with a virtual or CPU address that SNP provided
to convert it to a physical or device address. Since EFI uses the identical
mapping, this routine returns the physical address same as the virtual address
for most of the addresses. an address above 4GB cannot generally be used as a
device address, it needs to be mapped to a lower physical address. This routine
does not call the map routine itself, but it assumes that the mapping was done
at the time of providing the address to UNDI. This routine just looks up the
address in a map table (which is the v2p structure chain)

Routine Description:
This is a callback routine supplied to UNDI at undi_start time.
This is the IO routine for UNDI. This is not currently being used by UNDI3.0
because Undi3.0 uses io/mem offsets relative to the beginning of the device
io/mem address and so it needs to use the PCI_IO_FUNCTION that abstracts the
start of the device's io/mem addresses. Since SNP cannot retrive the context
of the undi3.0 interface it cannot use the PCI_IO_FUNCTION that specific for
that NIC and uses one global IO functions structure, this does not work.
This however works fine for EFI1.0 Undis because they use absolute addresses
for io/mem access.
Arguments:
ReadOrWrite - indicates read or write, IO or Memory
NumBytes - number of bytes to read or write
Address - IO or memory address to read from or write to
BufferAddr - memory location to read into or that contains the bytes
to write

Routine Description:

UNDI call this routine when it wants synchronize the virtual buffer contents

correspond to the same physical memory (especially if the virtual address is
> 4GB). Depending on the direction for which the buffer is mapped, undi will
need to synchronize their contents whenever it writes to/reads from the buffer
using either the cpu address or the device address.

the synchronization ourself here!

Routine Description:

Arguments:
snp - pointer to snp driver structure
BufferPtr - pointer to the memory for the received data
BuffSizePtr - is a pointer to the length of the buffer on entry and contains
the length of the received data on return
HeaderSizePtr - pointer to the header portion of the data received.
SourceAddrPtr - optional parameter, is a pointer to contain the source
ethernet address on return
DestinationAddrPtr - optional parameter, is a pointer to contain the destination
ethernet address on return
ProtocolPtr - optional parameter, is a pointer to contain the protocol type
from the ethernet header on return

// IMPORTANT NOTE:
// In case of the older 3.0 UNDI, if the input buffer address is beyond 4GB,
// DO NOT call the map function on the given buffer, instead use
// a global buffer. The reason is that UNDI3.0 has some unnecessary check of
// making sure that all the addresses (whether or not they will be given
// to the NIC ) supplied to it are below 4GB. It may or may not use
// the mapped address after all (like in case of CPB and DB)!
// Instead of using the global buffer whose address is allocated within the
// 2GB limit if I start mapping the given buffer we lose the data, here is
// why!!!
// if our address is > 4GB, the map call creates another buffer below 2GB and
// copies data to/from the original buffer to the mapped buffer either at
// map time or unmap time depending on the map direction.
// UNDI will not complain since we already mapped the buffer to be
// within the 2GB limit but will not use (I know undi) the mapped address
// since it does not give the user buffers to the NIC's receive unit,
// It just copies the received packet into the user buffer using the virtual
// (CPU) address rather than the mapped (device or physical) address.
// When the UNDI call returns, if we then unmap the buffer, we will lose
// the contents because unmap copies the contents of the mapped buffer into
// the original buffer (since the direction is FROM_DEVICE) !!!
//
// this is not a problem in Undi 3.1 because this undi uses it's map callback
// routine to map a cpu address to device address and it does it only if
// it is giving the address to the device and unmaps it before using the cpu
// address!
