Any chance someone could fix the SPF records for this mailing list?

[Alexander Duyck <alexander.duyck@gmail.com>]

I have noticed a number of emails from this list are going to spam.  It looks like it might be gmail filtering based on the fact that most of the list has a valid SPF based on an IPv4 address that reports out like below:
Received: from dpdk.org (dpdk.org. [92.243.14.124])
         by mx.google.com with ESMTP id eq6si3307415wib.54.2015.06.03.11.21.20;
         Wed, 03 Jun 2015 11:21:23 -0700 (PDT)
Received-SPF: pass (google.com: best guess record for domain of dev-bounces@dpdk.org designates 92.243.14.124 as permitted sender) client-ip=92.243.14.124;
Authentication-Results: mx.google.com;
        spf=pass (google.com: best guess record for domain of dev-bounces@dpdk.org designates 92.243.14.124 as permitted sender) smtp.mail=dev-bounces@dpdk.org

However the ones that are going straight into my spam folder list an IPv6 address that is rated neutral by the SPF:
Received: from dpdk.org ([2001:4b98:dc0:41:216:3eff:fe72:dd13])
         by mx.google.com with ESMTP id cy1si1185671wib.89.2015.06.03.04.00.32;
         Wed, 03 Jun 2015 04:00:37 -0700 (PDT)
Received-SPF: neutral (google.com: 2001:4b98:dc0:41:216:3eff:fe72:dd13 is neither permitted nor denied by best guess record for domain of dev-bounces@dpdk.org) client-ip=2001:4b98:dc0:41:216:3eff:fe72:dd13;
Authentication-Results: mx.google.com;
        spf=neutral (google.com: 2001:4b98:dc0:41:216:3eff:fe72:dd13 is neither permitted nor denied by best guess record for domain of dev-bounces@dpdk.org) smtp.mail=dev-bounces@dpdk.org

I was just wondering if it would be possible to get the IPv6 address added as a permitted sender for the domain to help reduce the amount of messages that are likely being flagged as spam for myself and likely others.

Thanks.
