Hi,
 
I could just send out one of these drivers and hope that it helps, but I thought it might be better to find out some more specifics on what is needed first. This way we can avoid lots thrashing and missed attempts at getting something to work.
 
What TEMAC core are you using? What version?
Is there a preference of linux kernels, 2.4 or 2.6?
If you prefer 2.6, do you already have the other kernel changes to support Virtex 4 (assuming that's the fpga you're using)?
 
Let me know what you're trying to accomplish so I can give you better specific help.
 
- John

    there is more than one implimentation of the ll_temac
    as well as m ore than one of the plb_temac.
    I have a combined 2.6 driver that I am working on.
       It works (or it did last time I tried it) for the ll_temac 
without the DMA engine.
       no interrupts, slow with a fairly high rate of dropped packets.
       The plb_temac portion is only for Fifo based plb_temacs, and is 
close but not quite working yet.
    It supports MII and autonegotiation (the last incarnation of the 
Xilinx MV driver I save posted did not.)
    I have used the Xilinx MV 2.6 driver - you can find links to it in 
the ML archives, seems to work well enough
    but is one speed - I forget which one. It is fairly simple to change 
the code to a different speed, but it does not support autonegotiation 
or MII.

    There is a monsterous patch to the linux-2.6 git tree at  
http://web.dlasys.net:8888/clients/pico/pico.patch that is for the Pico 
E12/E14 boards.
    Aside from the board support it includes My temac driver, The Xilinx 
MV edk driver, my Uartlite driver, Peter Korsgaard's Uartlite driver
    as well as in progress support for assorted other facets of the Pico 
E12/E14.

    You should be able to apply it to a 2.6.18 source tree, and have 
support for some additional Xilinx hardware for your board - BUT, most 
of the drivers
    require additional data in you board support code.
