Isn't sk->sk_prot a pointer to a global shared struct here still?  It looks like this would actually modify the global struct, and not just for this sk.
Yes, its global. It require add on check to modify only when tls_offload dev list has an entry. I will revisit and correct. Can you look through other changes please?

Thanks
