 # Currently it isn't possible to auto-tune the o2iblnd parameters optimally
 # inside the kernel since the OFED API hides the details from us.
 # Unfortunately, there isn't a single set of parameters that provide optimal
-# performance on different HCA/HFI types, so this file provides optimized
-# tunables based on the installed IB interface cards.
+# performance on different HCA/HFI types. This file provides optimized
+# tunables for the OPA cards.
+#
+# ** Please note that the below settings are the recommended settings only for
+#    OPA cards. If other IB cards are also present along with OPA cards then
+#    these settings will be applied across all the configured IB interfaces.
 #
 # Card detection and tunable selection is handled via /usr/sbin/ko2iblnd-probe
 # at runtime when the ko2iblnd module is installed, either at boot or when
 # Lustre is first mounted.
