This patch is simply clean-up to make the IPv4 type that is used match what Linux uses. It also attempts to move all variables that are IP addresses use good naming instead of CamelCase. No functional change. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
