This new mode is quite simple, I don't know if you have heard about PRP, but it's a new standard that allows to overcome any single network failure without affecting the data transmission. The general idea resides on having two separate LAN (A & B) very similar and transmitting the almost the same frame through both LANs and the end device should accept one frame and discard the other according to a known mechanism.

Isn't that the current 'broadcast' mode, where every packet is transmitted
over all the slaves? After quick googling/reading I don't see any
difference there, though I might have missed something.

You can find everything under Documentation/, but without the code I can't
tell you exact documents. CodingStyle and SubmittingPatches might be the
first ones.

Also, try CC-ing relevant people for more feedback, specifically bonding
maintainers.

Try sending an RFC when net-next opens.
