Routine Description: | |
This is the SNP interface routine for resetting the NIC | |
This routine basically retrieves snp structure, checks the SNP state and | |
calls the pxe_reset routine to actually do the reset! | |
Arguments: | |
this - context pointer | |
ExtendedVerification - not implemented | |
Returns: | |
