[RFC net-next 24/28] ip_tunnel: use ndo_siocdevprivate

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

 



From: Arnd Bergmann <arnd@xxxxxxxx>

The various ipv4 and ipv6 tunnel drivers each implement a set
of 12 SIOCDEVPRIVATE commands for managing tunnels. These
all work correctly in compat mode.

Move them over to the new .ndo_siocdevprivate operation.
