- qca-2.3 drop support for OSSL<1.1
- copy devel/qca to devel/qca-legacy which is held at the current version
- update devel/qca to 2.3
- Add Uses/qca.mk which handles dependency on either of the ports depending on the FreeBSD version
Users on FreeBSD11 must therefore change their pkg orign à la:
pkg set -o devel/qca:devel/qca-legacy
