net/smc: Dynamic control handshake limitation by socket options
This patch aims to add dynamic control for SMC handshake limitation for
every smc sockets, in production environment, it is possible for the
same applications to handle different service types, and may have
different opinion on SMC handshake limitation.
This patch try socket options to complete it, since we don't have socket
option level for SMC yet, which requires us to implement it at the same
time.
This patch does the following:
- add new socket option level: SOL_SMC.
- add new SMC socket option: SMC_LIMIT_HS.
- provide getter/setter for SMC socket options.
