Code Issues Proposed changes

Convert BOOTIF MAC to NIC name

Browse Source 
When booting via PXE one can set the ksdevice=bootif and add
'IPAPPEND 2' to the PXE boot config, this will set the MAC
address in the BOOTIF kernel cmdline which can then be used to
determine the NIC name to be used for the installation.

Tested with both valid and invalid input to BOOTIF=
