Ori,
Not just indentation. How about this modified text as well?

-       bit 0 - two hairpin ports loop
-       The default value is 0.
-       Hairpin will use single port mode and implicit Tx flow mode.
+       bit 0 - two hairpin ports loop (default)
+
+.. Note::
+
+   When hairpin is used in single port mode, Tx flow rule will be implicit.
Does this statement look right?
