actually i see it in drivers/staging/csr/
this is in netdev.c
here they do the below way
csr_xxx_ioctl(....) { int ret;
ret = -EOPNOTSUPP;
return ret; }
if the ioctl just needs to say that i am not going to support ioctl, then why we give the function address in the netdev_ops?
You're right, you should not have to. This is a staging driver though so the quality is not as good as a sane driver should look like, hence staging. Send a patch :)
Yes, sure right after the merge window gets closed. Thanks a lot,
as i understood from your reply that the dev_ioctl returns -EOPNOTSUPP when theres' no ioctl pointer registered in netdev_ops
am i right?
Yup.
