+====== Flow Control ======
+In some circumstances, you may wish to disable flow control.
+The exact method of this depends on the hardware involved, but here are a couple examples.
+All of these go in /boot/loader.conf.local:
+For em cards:
+<file bash /boot/loader.conf.local>
+hw.em.fc_setting = 0
+</file>
+or for igp cards:
+<file bash /boot/loader.conf.local>
+hw.igb.fc_setting = 0
+</file>
