Subject: Fix DHCP protocol so U-Boot does not respond too early
X-Git-Tag: v1.3.4-rc1~2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=0328ef0edfe950f0b7b8b368dae482531506b74a;p=u-boot

Fix DHCP protocol so U-Boot does not respond too early
on the network with it's offered IP number; it should not reply until
after it has received a DHCP ACK message. Also ensures that U-Boot
does it's DHCPREQUEST as broadcast (per RFC 2131).
