Right, seems I have somehow failed to use my search correctly.

Just ignore this task ;-)

Function is used in tcp_in.c twice

Some background on this function:

Each IPv6 neighbour has a reachability timer. When it expires, reachability needs to be confirmed.

Reachability is only confirmed when it is validated in both directions. ND6 NS and NA messages are used for this purpose.

Instead of sending ND6 messages for this purpose, it is acceptable to use an upper-layer indication that the neighbour is reachable.

The TCP layer is the recommended way to do it. A TCP ACK is considered a suitable hint of reachability. Then the reachable timer for that neighbor can be reset.
