Hi,
This is v2 of this RFC. Background information about this patch and HSR can be found in
the v1 submit: http://www.spinics.net/lists/netdev/msg192817.html.
This patch is now quite useable.
Known major functional problems:
* Sometimes, when used with slaves that are already up and using IPv6, no packets seem
to get through. (Possibly a bug in the driver for my slave interfaces - not sure yet.)
Other problems:
* There are a few FIXMEs that might need attention - except "reset status of slaves",
these are things I could use some help with.
* The kernel patch is against linux-next-120330 (so not quite up to date).
* The iproute patch is against iproute-2.6.35.
* The code needs cleanup, there are some commented debug printouts and such.
Major changes to v1:
* Added iproute patch.
* Fixed lockdep problem.
* Moved to Generic Netlink for HSR-specific userspace comms.
* Added userspace Generic Netlink example.
* Added HSR address substitution (so slaves kan keep their MAC addresses).
Part 1/2 contains the kernel patch (including the userspace example).
Part 2/2 contains the iproute patch (applies to iproute-2.6.35).
(I'm going on holiday on thursday so don't feel hurt if you write me and don't get a
reply. I'll check your messages when I get back early august though!)
