I've got a bag.

[  859.331626] [talos] controller failed {"component": "controller-runtime", "controller": "network.RouteSpecController", "error": "2 errors occurred:\n\t* error adding route: netlink receive: network is unreachable, message {Family:2 DstLength:0 SrcLength:0 Tos:0 Table:0 Protocol:3 Scope:0 Type:1 Flags:0 Attributes:{Dst:<nil> Src:141.1.1.2 Gateway:141.1.2.1 OutIface:4 Priority:1024 Table:254 Mark:0 Expires:<nil> Metrics:<nil> Multipath:[]}}\n\t* error adding route: netlink receive: network is unreachable, message {Family:2 DstLength:0 SrcLength:0 Tos:0 Table:0 Protocol:4 Scope:0 Type:1 Flags:0 Attributes:{Dst:<nil> Src:<nil> Gateway:141.1.2.1 OutIface:4 Priority:1025 Table:254 Mark:0 Expires:<nil> Metrics:<nil> Multipath:[]}}\n\n"}

dhcp params:

}

to up this route, Talos needs to pass special NextHop params (onlink):

ip route add default via 141.1.2.1 onlink dev eth0

I believe we need to add link route for the gateway here.
