When two interfaces are used for two VIPs, tie them together
When a node uses two physical interfaces for its two VIPs, these
physical interfaces should be tied together, so both VIPs will
be taken out of scheduling if either one fails. Without this change,
if a request comes into one interface that needs access to the
second interface to process the request, the original request
unnecessarily fails. Repeating this results in a black hole where
a failing server keeps getting new requests.
