Hello all,
I noticed that
ifconfig eth0 up
calls fec_open() and
ifconfig eth0 down
calls fec_close().
But fec_close() makes a call to fec_stop() which shuts
down the fec controller. fec_open() does not re-
initialize the controller again. And so, the ethernet
interface never works the second time around. Works
the first time since fec_init has set up init.
The fix is to remove the call to fec_stop() in
fec_close(). I've attached a patch that should work on
the MVista kernel 2.4.0 fec driver. An appropriate
location to call fec_stop() would be in cleanup_module
if the fec driver was a loadable kernel module.
Thank you,
Navin Boppuri.
