[openib-general] IPoIB multicast neighbour?!

[Or Gerlitz]

While debugging something, i have opened ipoib debug messages and see

	ib0: neigh_destructor for ffffff ff12:601b:ffff:0000:0000:0000:0000:0002

Do you have an idea what is the source of this neighbour? why it is created and
is there a way to eliminate this somehow (my guess is that removing IPv6 support
from the kernel will do that).

Its a RH4 U3 system with OFED 1.1 rc7

more info below, thanks.
