For L3 (bridged and routed) EX switches construct hash value from
several (6, IIRC) least significant bits of L3 and L4 addresses/ports.
MAC addresses (and only MAC addresses) are used for non IP bridged
traffic. So, say, (with an exception of EX8200, which can has labels)
all MPLS streams between a given pair of routers will follow a single
link in spite of labels and payload.
