Subject: [PATCH 49/62] Check PxeReplyReceived as fallback in netboot
00e791
00e791
Some mainboards do not update the ProxyOffset dhcp information when using
00e791
proxy dhcp and boot menus.
00e791
This adds a fallback to check the PxeReply field if no boot information is
00e791
found in the v4 dhcp or proxy dhcp information
