Subject: 6in4: https support for he.net tunnel api
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8f877ff42b88ec798af3237569b33907dada01e8;p=openwrt%2Fstaging%2Fstintel.git

6in4: https support for he.net tunnel api

HE.net tunnel update API requests are now made via https if an
SSL-capable wget is installed.  Certificate validation is
conditionally enabled if the CA certs are available.
