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.

I have removed the RFC tag and changed the patch series to formal
patch series from this version.

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 variable 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
 - Optimize the max_conns check in smc_clc_xxx_v2x_features_validate.
