from: Jeff Sloan <jeff_sloan at selinc.com> Update UEFI PXE proxyDHCP handling. This patch is based on commit ID 8a00e49 Modify two files to specify valid ip addresses. These files are efi/pxe.c and efi/udp.c. In efi/pxe.c: In net_parse_dhcp function. If ProxyOffer has been received, start with DhcpAck packet since it is the most complete. This requires a minimum of changes to the packet except that it contains...
