Subject: openvpn: add list element parsing
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=675eb747aa1cb76d4d6e715728592974acac8cc1;p=openwrt%2Fstaging%2Fxback.git

openvpn: add list element parsing

For the parameters tls-cipher and ncp-ciphers more than one option can
be used in the OpenVPN configuration, separated by a colon, which should
be implemented as a list in order to configure it more clearly. By
adding the new OPENVPN_LIST option to the openvpn.options file with the
tls-cipher and ncp-cipher parameters, uci can now add this option as a
"list" and the init script will generate the appropriate OpenVPN
configuration from it.
