OK, got it. At this point, I guess we should enhance the patch to use 
the values plugged into the IPv4 arp table at the time IPoIB is loaded, 
with arp_tbl being exported its easy to achieve. This would allow users 
to use non-default values by the ipoib neigh handling logic. In a later 
step, we need to see if/how to allow ipoib to use the already existing 
sysctl entries, makes sense?

Or.
