^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   18) 	Known limitations:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   19) 	Because of the way 3c509 ISA detection works it's difficult to predict
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   20) 	a priori which of several ISA-mode cards will be detected first.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   21) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   22) 	This driver does not use predictive interrupt mode, resulting in higher
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   23) 	packet latency but lower overhead.  If interrupts are disabled for an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   24) 	unusually long time it could also result in missed packets, but in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   25) 	practice this rarely happens.
