This patch set implement several new features in SMC v2.1(https://
www.ibm.com/support/pages/node/7009315), including vendor unique
experimental options, max connections per lgr negotiation, max links
per lgr negotiation.

v1 - v2:
 - rename field fce_v20 to fce_v2_base in struct
   smc_clc_first_contact_ext_v2x
 - use smc_get_clc_first_contact_ext in smc_connect
   _rdma_v2_prepare
 - adding comment about field vendor_oui in struct
   smc_clc_msg_smcd
 - remove comment about SMC_CONN_PER_LGR_MAX in smc_
   clc_srv_v2x_features_validate
 - rename smc_clc_clnt_v2x_features_validate

RFC v2 - v1:
 - more description in commit message
 - modify SMC_CONN_PER_LGR_xxx and SMC_LINKS_ADD_LNK_xxx
   macro defination and usage
 - rename field release_ver to release_nr
 - remove redundant release version check in client
 - explicitly set the rc value in smc_llc_cli/srv_add_link

RFC v1 - RFC v2:
 - Remove ini pointer NULL check and fix code style in
   smc_clc_send_confirm_accept.
 - Optimize the max_conns check in smc_clc_xxx_v2x_features_validate.
