network: add support for HSR netdev

Browse Source 
Add support for creating HSR/PRP interfaces. HSR (High-availability Seamless
Redundancy) and PRP (Parallel Redundancy Protocol) are two protocols that
provide seamless failover against failure of any single network component. They
are both implemented by the "hsr" kernel driver.
