@ -2284,6 +2284,19 @@ config GELIC_WIRELESS
the driver automatically distinguishes the models, you can
safely enable this option even if you have a wireless-less model.
config GELIC_WIRELESS_OLD_PSK_INTERFACE
bool "PS3 Wireless private PSK interface (OBSOLETE)"
depends on GELIC_WIRELESS
help
This option retains the obsolete private interface to pass
the PSK from user space programs to the driver. The PSK
stands for 'Pre Shared Key' and is used for WPA[2]-PSK
(WPA-Personal) environment.
If WPA[2]-PSK is used and you need to use old programs that
support only this old interface, say Y. Otherwise N.
If unsure, say N.
config GIANFAR
tristate "Gianfar Ethernet"
depends on FSL_SOC
