+driver was written by

+.Sh CAVEATS
+While the firmware supports reading module information for
+.Xr ifconfig 8
+.Cm transceiver
+to use, it does not support writing to the module.
+This prevents configuration of the module, which may prevent
+.Xr ifconfig 8
+from reading the right data from the module where other network
+cards succeed.
