- Use the PCI IO abstraction to issue memory or I/O reads and writes. This is also the routine which\r
- gets replaced during RunTime by the O/S in the NIC_DATA_INSTANCE so it can do it's own I/O abstractions.\r
-\r
-Arguments:\r
-\r
- UnqId - Runtime O/S routine may use this field, this temp routine does not.\r
-\r
- ReadWrite - Determine if it is an I/O or Memory Read/Write Operation.\r
-\r
- Len - Determines the width of the data operation.\r
-\r
- Port - What port to Read/Write from.\r
-\r
- BuffAddr - Address to read to or write from.\r
-\r
-Returns:\r
-\r
- none\r

-Routine Description:\r
-\r
- Using the NIC data structure information, read the EEPROM to get the MAC address and then allocate space\r
- for a new devicepath (**DevPtr) which will contain the original device path the NIC was found on (*BaseDevPtr)\r
- and an added MAC node.\r
-\r
-Arguments:\r
-\r
- DevPtr - Pointer which will point to the newly created device path with the MAC node attached.\r
-\r
- BaseDevPtr - Pointer to the device path which the UNDI device driver is latching on to.\r
-\r
- AdapterInfo - Pointer to the NIC data structure information which the UNDI driver is layering on..\r
-\r
-Returns:\r
-\r
- EFI_SUCCESS - A MAC address was successfully appended to the Base Device Path.\r
-\r
- other - Not enough resources available to create new Device Path node.\r
