-/* NOTE:
- * There are three outstanding bug/features in this implementation.
- * They may even be hardware misfeatures. The conditions are registered
- * by counters maintained by the software.
- * 1: over_write is a condition that means that the board wants to store
- * packets, but there is no room. So new packets are lost. What seems to
- * be happening is that we get an over_write condition, but there are no
- * or just a few packets in the board's ram. Also it seems that we get
- * several over_writes in a row.
- * 2: Since there is only one transmit buffer, we need a lock to indicate
- * whether it is in use. We clear this lock when we get a transmit interrupt.
- * Sometimes we go to transmit and although there is no transmit in progress,
- * the lock is set. (In this case, we just ignore the lock.) It would look
- * like we can miss transmit interrupts?
- * 3: We tried to clean up the unnecessary switches to bank 0.
- * Unfortunately, when you do an ifconfig "down", the system tend to lock up
- * a few seconds later (this was when DSF_RUNNING) was not being set before.
- * But even with DSF_RUNNING, on an EISA bus machine we ALWAYS lock up after
- * a few seconds.
