Will not apply to current iproute source. The header files have been updated to be from current upstream (linus), and the IFLA_HSR doesn't match.

Please fix, and resubmit. Note, for iproute2 the header files are updated perodically by using headers from kernel source (sanitized).

usr/include/linux/if_link.h

/* HSR section */

enum {
        IFLA_HSR_UNSPEC,
        IFLA_HSR_SLAVE1,
        IFLA_HSR_SLAVE2,
        IFLA_HSR_MULTICAST_SPEC,
        __IFLA_HSR_MAX,
};

#define IFLA_HSR_MAX (__IFLA_HSR_MAX - 1)

So, what's the least annoying (for everyone) way of getting the updated header file into the kernel _and_ iproute?

I guess the iproute patch should be against net-next-for-3.13? (The HSR kernel patch was picked up into 3.13-rc1.)

And the updated kernel patch (with the .fill_info routine implemented and the updated header file), where do I send that?
