\fBovs\-vswitchd\fR started through \fBovs\-ctl\fR(8) provides a limit of 65535
file descriptors. The limits on the number of bridges and ports is decided by
the availability of file descriptors. With the Linux kernel datapath, creation
-of a single bridge consumes three file descriptors and adding a port consumes
-"n-handler-threads" file descriptors per bridge port. Performance will degrade
-beyond 1,024 ports per bridge due to fixed hash table sizing. Other platforms
+of a single bridge consumes three file descriptors and each port
+consumes one additional file descriptor. Other platforms
may have different limitations.
