WiMAX can work without RFKILL, but it was missing a check to make sure RFKILL is not being made a module with wimax compiled into the kernel. This caused failed builds in s390, where CONFIG_INPUT is always off. When RFKILL is enabled, the code uses the input layer to report hardware switch changes; thus, if RFKILL is enabled, INPUT has to be too. It also needs to display some message when INPUT is disabled that explains why WiMAX is not selectable. (issues found by Randy Dunlap in the linux-next tree).

# Note the ugly 'depends on' on WIMAX: that disallows RFKILL to be a
|
|
# module if WIMAX is to be linked in. The WiMAX code is done in such a
|
|
# way that it doesn't require and explicit dependency on RFKILL in
|
|
# case an embedded system wants to rip it out.
|
|
#
|
|
# As well, enablement of the RFKILL code means we need the INPUT layer
|
|
# support to inject events coming from hw rfkill switches. That
|
|
# dependency could be killed if input.h provided appropiate means to
|
|
# work when input is disabled.

Select to configure support for devices that provide
|
|
wireless broadband connectivity using the WiMAX protocol
|
|
(IEEE 802.16).
|
|
|
|
Please note that most of these devices require signing up
|
|
for a service plan with a provider.
|
|
|
|
The different WiMAX drivers can be enabled in the menu entry
|
|
|

Device Drivers > Network device support > WiMAX Wireless
|
|
Broadband devices

If unsure, it is safe to select M (module).

Select the maximum debug verbosity level to be compiled into
|
|
the WiMAX stack code.
|
|
|
|
By default, debug messages are disabled at runtime and can
|
|
be selectively enabled for different parts of the code using
|
|
the sysfs debug-levels file.
|
|
|
|
If set at zero, this will compile out all the debug code.
|
|
|
|
It is recommended that it is left at 8.
