I already have patches that implement full kernel support for the 6-path format, and globally enable APM. With this netlink interface it becomes feasible to mainline them. That will require some reworking of what you've done, but I don't expect you to do that. The only remaining thing we need here is that tiny bit of policy information for the kernel to specify what the intended use of the path is: - For connected CM operation (6 path records) - For unidirectional UD (1 path record) - For 'misc' GMP like operation (at least 1 reversible path record) I'm happy if you call it PATH_USE_XX Testing the reversible bit should be enough to rough this in, if not reversible it is PATH_USE_UNIDIRECTIONAL_UD, otherwise it is PATH_USE_GMP. Recommend that userspace treat any unknown usage type as GMP (it is the most general). Ira: Do you like 'path use' better as a name? I think I do..
