Subject: pxe: make the first label the implicit default
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6f40f2749ac34da91c7054ee6d94808ee1db4cb1;p=project%2Fbcm63xx%2Fu-boot.git

pxe: make the first label the implicit default

If no default label is specified, but a situation arises where the
default label should be used, treat the first label specified as the
default label.
