@@ -258,3 +258,19 @@ Why: These drivers never compiled since they were added to the kernel
Who: Jean Delvare <khali@linux-fr.org>
---------------------------
What: Bridge netfilter deferred IPv4/IPv6 output hook calling
When: January 2007
Why: The deferred output hooks are a layering violation causing unusual
and broken behaviour on bridge devices. Examples of things they
break include QoS classifation using the MARK or CLASSIFY targets,
the IPsec policy match and connection tracking with VLANs on a
bridge. Their only use is to enable bridge output port filtering
within iptables with the physdev match, which can also be done by
combining iptables and ebtables using netfilter marks. Until it
will get removed the hook deferral is disabled by default and is
only enabled when needed.
Who: Patrick McHardy <kaber@trash.net>
