There shouldn't be any need to add a new attribute. The RTA_VIA
attribute that Eric Biederman recently introduced should have the
semantics that you require:

"RTA_VIA specifies the specifies the next machine to send a packet to
like RTA_GATEWAY. RTA_VIA differs from RTA_GATEWAY in that it
includes the address family of the address of the next machine to send
a packet to."
