-# Specifies the maximum number of outstanding requests that can be in

-# parallelism, but increases system resource usage and subnet load.
-# If the number of pending requests is greater than the send_depth,
-# the additional requests will automatically be queued until some of
-# the previous requests complete.
+# Specifies the number of outstanding send operations that can
+# be in progress simultaneously. A larger send depth consumes
