IPv6: Make link-local configurable per-interface (VPP-1446)
Remove old nonfunctional code for setting link-local addresses. Use common API for setting all IPv6 addresses. Change-Id: I562329df86341f81ef2441510a9eefbbf710f6e0 Signed-off-by: Juraj Sloboda <jsloboda@cisco.com> Signed-off-by: Matus Fabian <matfabia@cisco.com>
