Subject: When printing MAC addresses, always use trailing zeroes.
X-Git-Tag: release-1.1pre11~82
X-Git-Url: http://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=dc55691ca7399bab28963f92e4c3dea9d6bf8eb1

When printing MAC addresses, always use trailing zeroes.

tinc currently prints MAC addresses without trailing zeroes, for example:

    1:2:3:4:5:6

This looks weird and is inconsistent with how MAC addresses are
displayed everywhere else. This commit adds trailing zeroes, so the
above address will be printed as the following:

    01:02:03:04:05:06
