-Abstract:

- This file contains two sets of callback routines for undi3.0 and undi3.1.

- the callback routines for Undi3.1 have an extra parameter UniqueId which

- stores the interface context for the NIC that snp is trying to talk..

-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)

-

-Arguments:

- CpuAddr - virtual address of a buffer

- DeviceAddrPtr - pointer to the physical address

-

-Returns:

- void - The DeviceAddrPtr will contain 0 in case of any error

-  )

-/*++

-

-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
