when I try to add sudo ip route add 10.248.5.0/24 dev bond0.250 table vlan_250 src 10.248.5.154

I get RTNETLINK answers: Invalid argument

On latest 4.3 compiled from source on ubuntu 14.04

It is not ip route but the kernel that is complaining.
The reason it is invalid is most likely that 10.248.5.154 is not an ip address on that interface.

bond0.250 Link encap:Ethernet  HWaddr d2:ad:06:04:ba:c9

the command also works fine if i go back to kernel 4.2.1
