[RFC net-next 1/2] drivers/net: Create an ANCIENT_NETDEVICES symbol

From: Joe Perches
Date: Fri Mar 18 2016 - 20:33:56 EST

Many drivers are ancient and written for hardware that is no longer
available. These drivers are effectively untested under current
kernels. Add a symbol that could guard inclusions of these drivers
into modern kernels unless specifically requested.

+ Many old devices are no longer manufactured.
+ The drivers for these devices likely worked with the original
+ kernel version when the devices were manufactured, but do not
+ necessarily function well today.
+ If these devices still exist and are still functional, the drivers
+ for these devices get scant testing.
+ The drivers for these devices are unmaintained and not supported by

+ If you are unsure that you need drivers for old hardware, say N.
# All the following symbols are dependent on NETDEVICES - do not repeat
