Re: [ovs-dev] [PATCH v2] datapath: Fix build errors for 4.9.172+ kernels
Thanks Yi-Hung for the review.
4.9 kernel is using ip6frag_init instead of ip6_frag_init, so the
original change
is essential. Otherwise, there will be compiling errors:
https://travis-ci.org/yifsun/ovs-travis/builds/536900954
I will add /* HAVE_INET_FRAGS_RND */ and submit a new version.

Hi Yifeng,
Thanks for the update. Are we replicating "nf_frags.constructor =
ip6_frag_init;" for the 3 cases?
How about the following change?

[ovs-dev] [PATCH v2] datapath: Fix build errors for 4.9.172+ kernels
4.9.172+ kernel backported upstream patch 70b095c843266
("ipv6: remove dependency of nf_defrag_ipv6 on ipv6 module")
and this caused compilation errors of OVS kernel module.
This patch fixes it by checking and using new functions
introduced by the upstream patch.
Travis tests passed at
https://travis-ci.org/yifsun/ovs-travis/builds/536527230
with latest Linux kernel version.
In addition, this patch doesn't introduce failed tests for latest kernels
of Ubuntu (bionic, trusty, xenial), fedora, centos 73, rhel (74, 75, 76).
Reported-by: Ilya Maximets
Signed-off-by: Yifeng Sun

v1->v2: Fixed at bug that crashes certain kernels. Thanks YiHung!
