The LPI translation cache needs to be discarded when an ITS command may affect the translation of an LPI (DISCARD, MAPC and MAPD with V=0) or the routing of an LPI to a redistributor with disabled LPIs (MOVI, MOVALL). We decide to perform a full invalidation of the cache, irrespective of the LPI that is affected. Commands are supposed to be rare enough that it doesn't matter.
