Only if the fl4.saddr wasn't set before:
if (!fl4->saddr)
fl4->saddr = FIB_RES_PREFSRC(net, res);
But i have (or need) a fl4->saddr since i want "ip rules" to be
inspected as well, and with an ip rule with "from $SRC" i need to call
ip_route_output_key(dev_net(dev), &fl4) with an fl4->saddr set or the
rule won't match correctly.
In the past i could call "ip_route_output_key" and then use "rt->rt_src"
to get the source ip i needed.
