Hello all,
Can I use ddi_copyout in a solaris NIC driver?
(I want to transfer more than 2K data to the user land through ioctl
interface in a nic driver.)
Also, in the man page of ddi_copyout, I came across the below statement
This routine is designed for use in driver ioctl(9E) rou-
tines for drivers that support layered ioctls.
What does "layered ioctls" mean here? How can I know if the driver is
supporting layered ioctls or not?
Thanks much in advance for the help!
