PXE Boot supporting 802.1x authentication
It appears PXE 3.0 is capable of supporting 802.1x authentication.
Many networks utilize radius authentication to control users and VLANs. This is an issue with the current K2000 PXE since there is no option to provide credentials. I suggest an option be added to insert a username and password into the undionly.kpxe and ipxe.efi so that PXE Boot can authenticate.
