Subject: pxe: simplify menu display and selection
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-favicon.png?a=commitdiff_plain;h=32d2ffe7316b39fbeb38525e9445601cb39276fd;p=u-boot.git

pxe: simplify menu display and selection

Menus with lots of entries and long append lines are hard to read.
Just show a numbered list using the label or name and make the choice
by entering the number.
