-Routine Description:\r
- This is the SNP interface routine for starting the interface\r
- This routine basically retrieves snp structure, checks the SNP state and\r
- calls the pxe_start routine to actually do start undi interface\r
-\r
-Arguments:\r
- This - context pointer\r
-\r
-Returns:\r
- EFI_INVALID_PARAMETER - "This" is Null\r
- - No SNP driver can be extracted from "This"\r
- EFI_ALREADY_STARTED - The state of SNP is EfiSimpleNetworkStarted\r
- or EfiSimpleNetworkInitialized\r
- EFI_DEVICE_ERROR - The state of SNP is other than EfiSimpleNetworkStarted,\r
- EfiSimpleNetworkInitialized, and EfiSimpleNetworkStopped\r
- EFI_SUCCESS - UNDI interface is succesfully started\r
- Other - Error occurs while calling pxe_start function.\r
