Subject: [PATCH net-next 0/4] net/smc: Add SMC statistic support

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

The patchset adds statistic support to the SMC protocol. Per-cpu
variables are used to collect the statistic information for better
performance and for reducing concurrency pitfalls. The code that is
collecting statistic data is implemented in macros to increase code
reuse and readability.
The generic netlink mechanism in SMC is extended to provide the
collected statistics to userspace.
Network namespace awareness is also part of the statistics
implementation.

Guvenc Gulce (4):
  net/smc: Add SMC statistics support
  net/smc: Add netlink support for SMC statistics
  net/smc: Add netlink support for SMC fallback statistics
  net/smc: Make SMC statistics network namespace aware
