[NET]: Mark frame diverter for future removal.
The code for frame diverter is unmaintained and has bitrotted. The number of users is very small and the code has lots of problems. If anyone is using it, they maybe exposing themselves to bad packet attacks. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>

+What: frame diverter
+When: November 2006
+Why: The frame diverter is included in most distribution kernels, but is
+ broken. It does not correctly handle many things:
+ - IPV6
+ - non-linear skb's
+ - network device RCU on removal
+ - input frames not correctly checked for protocol errors
+ It also adds allocation overhead even if not enabled.
+ It is not clear if anyone is still using it.
