The new socket family is assigned the next available address / protocol
family constant 41.
Implementing SO_KEEPALIVE for SMC-R requires an extra hook in net/ipv4/timer.c.

The SMC-R protocol defines dynamic discovery of peers. This is done by
implementing experimental TCP options as defined in RFC6994. The TCP code
needs to be extended to support RFC6994.

To activate the smc-specific hooks in the TCP-code, static key tcp_have_smc
is increased and decreased. For now this is done at module load / unload time.

Eric,
this is V2 of my SMC-R patches, containing especially a new version of the
required tcp changes. As you suggested, SMC-specific hooks in the TCP-code
are built only for CONFIG_AFSMC. And I come up with helpers in include files
to avoid spreading

Eric,
understood, would it be acceptable if the SMC-specific hooks in the
TCP-code are enclosed with #ifdef CONFIG_SMC ... #endif?
