Log:
  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.
