Dave,

thanks for your feedback and pointing out the kernel_setsockopt()
problem(s) in patch 2/4. Here is now version 2 of the patch series
with patches 2-4 implementing sockopts that require special
handling in SMC.

Version 2 changes of Patch 2/4 (and 3/4):
   * return error -EOPNOTSUPP for TCP_FASTOPEN sockopts
   * fix a kernel_setsockopt() usage bug by switching parameter
     variable from type "u8" to "int"
   * add return code validation when calling kernel_setsockopt()
   * propagate a setsockopt error on the internal CLC socket
     to the SMC socket.

Regards, Ursula
