A few specific questions (based on my perusal of the edb7xxx
driver):

1) The DSR that is called now seems to be a generic Ethernet
   DSR which then arranges for a future call to the "deliver"
   callback pointing to what used to be the driver DSR.

   The "deliver" callback is called from a thread context
   rather than a DSR context.
   
   Right?

2) What is the "poll" callback in ETH_DRV_SC for?  It seems to
   do almost the exact same thing that the deliver callback
   does.

3) What is done with the return value from the int_vector
   callback?  My driver uses three different interrupts, and
   I'm not sure which one to put here.  I'm guessing it's the
   interrupt number for the interrupt that calls the DSR that
   does mostly the same thing as the "deliver" callback?

4) The poll() and int_vector() callbacks seem not to be unused
   in "net/eth_drv.c" and are used only in stand_alone/eth_drv.c.
   Can I just put in stubs that do nothing for those two?
