This is not a bug report, but a feature request.
routing policy database management is supported since linux 2.2, but it lacks
u32 selector (matching by IP protocols, transport ports).
fwmark is a workaround for this missing feature, but source ip address
selection will not work anyway: the mark value can't be used for source address
selection because at the time source address selection is performed, there is
no packet yet and thus no mark value.
