[PATCH v3 net-next 7/9] ila: Resolver mechanism

Implement an ILA resolver. This uses LWT to implement the hook to a userspace resolver and tracks pending unresolved address using the backend net resolver. The idea is that the kernel sets an ILA resolver route to the SIR prefix, something like: ip route add ::/64 encap ila-resolve \
