 Miscellaneous Notes
 -------------------
 
+Open vSwitch source code uses uint16_t, uint32_t, and uint64_t as
+fixed-width types in host byte order, and ovs_be16, ovs_be32, and
+ovs_be64 as fixed-width types in network byte order.  Each of the
+latter is equivalent to the one of the former, but the difference in
+name makes the intended use obvious.

 ovs-vswitchd is the most sophisticated of ofproto's clients, but
-ofproto can have other clients as well.  ovs-openflowd, in the
-utilities directory, is much simpler than ovs-vswitchd.  It may be
-easier to initially bring up ovs-openflowd as part of a port.

 lib/entropy.c assumes that it can obtain high-quality random number
 seeds at startup by reading from /dev/urandom.  You will need to
