Roland,

The issue came up during gen1 IPoIB debug. 
As far as I was able to track it, header_cache_update() was not called
upon MAC address update, so I had to add an explicit check 
in the IPoIB code verifying the data in neighbor->ha and in path->... are
consistent 
and if not - invalidating the old AH and starting get_path_record flow.

I'm not sure if this could really happen or not.  But could we add a
header_cache_update() method to the IPoIB struct net_device to handle this
situation if it does occur?
