IPoIB: Handle P_Key table reordering
SM reconfiguration or failover possibly causes a shuffling of the values in the P_Key table. Right now, IPoIB only queries for the P_Key index once when it creates the device QP, and hence there are problems if the index of a P_Key value changes. Fix this by using the PKEY_CHANGE event to trigger a recheck of the P_Key index. Signed-off-by: Yosef Etigin <yosefe@voltaire.com> Acked-by: Michael S.
