RE: [ECOS] Is it possible to do polling for the Ethernet driver using a stack ?

["Cusson, Pascal" <pascal dot cusson at analog dot com>]

Yes there is,
   I need maximize performance on a system will support multiple ATM and
ETH. My system need to be synchronous meaning one after another in
specific order. By using polling I can easily control all aspects.
Further more, polling will take less time than using interrupts which
should help for performances. The 8260 I am using is not the fastest
therefore I need everything I can get out of it.

   What I would like do is poll the FCCE to see if there is a buffer
ready and then signal the stack so that the buffer descriptor can be
processed and freed. 

The part I am missing here is how to I tell the stack to process my
buffer descriptor ?

The stacks that are used with eCos (not RedBoot, it has it's
own stack) really should be interrupt driven.  Is there some
reason that you want to poll?
