I feel like it's better to always log the "Initializing SDN" message... can you move things around so that happens before this? (And why did you move this before setNodeIP? Why does that matter?)

Agree, it is always good to log this msg.
This proxy check doesn't depend on computing hostname/selfIP, so I just moved that logic a bit up in this method.

This is not the same as what findEgressLink() was doing. The netlink.Addr's embedded IPNet is an IP address (eg "172.17.0.3/24"), but eip.localEgressNet is supposed to be the subnet CIDR that includes it (eg "172.17.0.0/24"). Hence the re-parsing of it (because there's no public method to directly mask the IP address form into the subnet form).
Check proxy mode in node.New() before computing hostname/selfIP so that we can return early in case of incompatible proxy mode error.

Automatic merge from submit-queue. Fix cross build #17043 broke the cross build by depending on netlink from pkg/network/common. This fixes that (by just moving the new function since it wasn't needed outside of pkg/network/node anyway).
