From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jakub Sitnicki Subject: [PATCH net-next 2/5] net: Extend struct flowi6 with multipath hash Date: Mon, 24 Oct 2016 11:28:49 +0200 Message-ID: <1477301332-23954-3-git-send-email-jkbs@redhat.com> References: <1477301332-23954-1-git-send-email-jkbs@redhat.com> Cc: linux-kernel@vger.kernel.org, "David S. Miller" To: netdev@vger.kernel.org Return-path: In-Reply-To: <1477301332-23954-1-git-send-email-jkbs@redhat.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Allow for functions that fill out the IPv6 flow info to also pass a hash computed over the skb contents. The hash value will drive the multipath routing decisions. This is intended for special treatment of ICMPv6 errors, where we would like to make a routing decision based on the flow identifying the offending IPv6 datagram that triggered the error, rather than the flow of the ICMP error itself.
