Subject: Use the proper types for comma separated attributes read from strongswan.conf
X-Git-Tag: 5.0.1~135
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4065e2504c9939cf823c661eaef33ffeb530f9da;p=thirdparty%2Fstrongswan.git

Use the proper types for comma separated attributes read from strongswan.conf

Attributes of different address families previously were mapped to
the same attribute type (the one derived from the address family of the
first address).
