Subject: efinet: add structures for PXE messages
|
|
|
|
When grub2 image is booted from UEFI IPv6 PXE, the DHCPv6 Reply packet
|
|
is cached in firmware buffer which can be obtained by PXE Base Code
|
|
protocol. The network interface can be setup through the parameters in
|
|
that obtained packet.
|
|
|
|
Augment existing structures to represent this, and make them agnostic
|
|
between ipv4 and ipv6.
