I have been trying to find out,  how can I set these below values,  if I use Luster & LNET using 25 gbps Ethernet network.   Seems like for Infiniband or Intel OPA,  you can set them in ko2iblnd.conf.  



              peer_timeout: 180
              peer_credits: 8
              peer_buffer_credits: 0
              credits: 256
lnd tunables:

              peercredits_hiw: 64

              map_on_demand: 32

              concurrent_sends: 256

              fmr_pool_size: 2048

              fmr_flush_trigger: 512

              fmr_cache: 1


Also,  I have been doing Dynamic Network Configuration using lnetctl command, in that case,  is there a way to set the above values or it has to be via some config file only?
