Subject: Use of 'SIOCDEVPRIVATE' in ethernet drivers.

I'm implementing a new interface for upgrading the firmware for our next
generation of Qlogic drivers. We need to transfer control information
between userspace and driver, in addition to the firmware payload. I'm
considering using 'SIOCDEVPRIVATE' ioctl interface to pass control
information between userland and driver.

I also see comments in the source (include/linux/sockios.h) that
'SIOCDEVPRIVATE' will be deprecated 2.5.x. What is the current status of
deprecation in the latest versions of the kernel?

Are we still allowed to use 'SIOCDEVPRIVATE' in drivers if there the
deprecation efforts are on hold.

Any input will be appreciated.

Thanks.
Giri
