[RFC net-next 25/28] hippi: use ndo_siocdevprivate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnd Bergmann <arnd@xxxxxxxx>

The rr_ioctl uses private ioctl commands that correctly pass
all data through ifr_data, which works fine in compat mode.

Change it to use ndo_siocdevprivate as a cleanup.
