Author: hselasky Date: Fri Mar 30 18:25:30 2018 New Revision: 331774 URL: https://svnweb.freebsd.org/changeset/base/331774 Log: MFC r330492: Add support for IPv6 link local GIDs equal to the default GID for VLANs in ibcore. IPv6 link local addresses are usually derived from the netdev MAC address. This is applicable to VLAN devices and its lower netdevice as well. In such cases the IPv6 link local address is a duplicate of the default GID. Now that link local IPv6 addresses based GIDs are supported, allow adding such GID entries in the GID table.
