Hello Dave,

There is agreement that the user-space API for using the SMC protocol must
be changed, namely by dropping AF_SMC and by making applications use the
SMC protocol through socket(AF_INET..., SOCK_STREAM, ...). What is your
plan to avoid that applications start using and depending on AF_SMC?

Thanks,

Bart.
