Guangguan Wang 1f2c9dd73f net/smc: add sysctl for max conns per lgr for SMC-R v2.1
Add a new sysctl: net.smc.smcr_max_conns_per_lgr, which is
used to control the preferred max connections per lgr for
SMC-R v2.1. The default value of this sysctl is 255, and
the acceptable value ranges from 16 to 255.
