Up to version 4 this patch series was using the sock_diag netlink infrastructure. This version is using the generic netlink API. Generic netlink API offers a better type safety between kernel and userspace communication. Using the generic netlink API the smc module can now provide information about SMC linkgroups, links and devices (both for SMC-R and SMC-D). v2: Add missing include to uapi header smc_diag.h. v3: Apply code style recommendations from review comments. Instead of using EXPORTs to allow the smc_diag module to access data of the smc module, introduce struct smc_diag_ops and let smc_diag access the required data using function pointers. v4: Address checkpatch.pl warnings. Do not use static inline for functions. v5: Use generic netlink API instead of the sock_diag netlink infrastructure. v6: Integrate more review comments from Jakub.
