Please apply the following patch series for smc to netdev's net-next tree.

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.

Guvenc Gulce (13):
  net/smc: Use active link of the connection
  net/smc: Add connection counters for links
  net/smc: Add link counters for IB device ports
  net/smc: Add diagnostic information to smc ib-device
  net/smc: Add diagnostic information to link structure
  net/smc: Refactor smc ism v2 capability handling
  net/smc: Introduce generic netlink interface for diagnostic purposes
  net/smc: Add support for obtaining system information
  net/smc: Introduce SMCR get linkgroup command
  net/smc: Introduce SMCR get link command
  net/smc: Add SMC-D Linkgroup diagnostic support
  net/smc: Add support for obtaining SMCD device list
  net/smc: Add support for obtaining SMCR device list

Karsten Graul (1):
  net/smc: use helper smc_conn_abort() in listen processing
