1) Adjust NFRAMES from 16 to 8 per 16k of memory.
2) Acknowledge interrupts to the card early in the interrupt
handler before processing the event that caused the interrupt.
This frees the card to process addtional events instead of
waiting for the driver to finish handling events.
3) Changed the initialization of the transmit buffers to be a
loop so that the number of buffers can be more easily changed.
4) Moved the code to take the adapter out of loop back mode to just
before we enable the receiver.
I also made the driver dynamically size its resource arrays at attach
time so that we can take full advantage of adapters with more than 16k
of memory.
Richard has some other changes he's working on to improve performance,
but this should get ee16 support working reliably again.
Thanks to Wes Santee <wes@bogon.net> for testing these patches.
