`own_ipv6` in `dp_port` structure

[PlagueCZ]

field own_ipv6 is basically unused:

plague@smrcek ~/git/dpservice $ grep -rn own_ipv6 src/
src/nodes/ipv6_nd_node.c:80:            dp_copy_ipv6(&port->iface.cfg.own_ipv6, dp_get_dst_ipv6(req_ipv6_hdr));
plague@smrcek ~/git/dpservice $ grep -rn own_ipv6 include/
include/dp_port.h:31:   union dp_ipv6                   own_ipv6;

In contrast with own_ip which is used in many places (gRPC, ARP, DHCP, ...).

But there is also dhcp_ipv6 which is actually used almost like own_ip above.

Am I missing something or should these be merged?

As discussed. The line dp_copy_ipv6(&port->iface.cfg.own_ipv6, dp_get_dst_ipv6(req_ipv6_hdr)); can be eliminated and dhcp_ipv6 can be renamed to own_ipv6.
