Who: Patrick McHardy <kaber@trash.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.
+Who: Stephen Hemminger <shemminger@osdl.org>
