In u-boot printf has been extended with the %pM formatter to allow printing of MAC addresses. However buffers that want to store a MAC address cannot safely get the size. Add a define for this case so the string of a MAC address can be reliably obtained. Signed-off-by: Olliver Schinagl <oliver@schinagl.nl> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
