This set converts Intel drivers which have the ability to spawn multiple netdevs, but have only one UDP tunnel port table.
Appropriate support is added to the core infra in patch 1, followed by netdevsim support and a selftest. The table sharing works by core attaching the same table structure to all devices sharing the table. This means the reference count has to accommodate potentially large values. Once core is ready i40e and ice are converted. These are complex drivers, and I don't have HW to test so please review..
