Another approach may be to tie the unsub from sendonly multicast joins to
the expiration of the layer 2 addresses in IPoIB. F.e. add code to
 __ipoib_reap_ah() to detect if the handle was used for a sendonly
multicast join. If so unsubscribe from the MC group. This will result in
behavior consistent with address resolution and caching on IPoIB.

yep, Erez has the patches to do so.

Would you please share them?
