FINALLY !!!!!!!!!!!!!!!!!
I was able to make it work this morning...
By playing around with the registers, I figured out that in order to
correct the media select routine, we had to do
a two step programming of the csr6 register.
Unfortunately, the driver plays around with this register and it was
not possible to configure
it from the media select routine.
I decided to put the final configuration of csr6 in the sysLanIntEnable
routine...
That did it !!!!!!
Here are my mediaSelect and sysLanIntEnable routines...
/***********************************************************************

return (OK);
}

> Hi,
