iPXE cannot do dhcp with: Could not configure net0

[robinsmidsrod]

Just for reference, the code set cached 0 has no effect on the dhcp command. As of a recent 2014 commit, the dhcp command will always request a new lease from the dhcp server. If you want to use the same feature that was previously supported by set use-cached 1, you only need to use ifopen instead of dhcp to open the interface. The previous IP from the chainload will already be set on the interface.
