net/hsr: Added support for HSR v1
This patch adds support for the newer version 1 of the HSR networking standard. Version 0 is still default and the new version has to be selected via iproute2. Main changes are in the supervision frame handling and its ethertype field. Signed-off-by: Peter Heise <peter.heise@airbus.com> Signed-off-by: David S. Miller <davem@davemloft.net>
