+	Known limitations:
+	Because of the way 3c509 ISA detection works it's difficult to predict
+	a priori which of several ISA-mode cards will be detected first.
+
+	This driver does not use predictive interrupt mode, resulting in higher
+	packet latency but lower overhead.  If interrupts are disabled for an
+	unusually long time it could also result in missed packets, but in
+	practice this rarely happens.
