The BPF infrastructure in kernel changed which broke the method
being used to load the RSS part of rte_flow in the TAP device.
Since this is a little used feature, and fixing the problem would
be moderately complex and create new dependency on libbpf,
mark the feature as deprecated and plan for removal.
Does this mean that RSS will not work with netvsc as netvsc is using tap and mellanox ? Or will that not be affected .
