    Date
    From: Paolo Pisati <paolo.pisati@canonical.com>

    [ Upstream commit aba69d49fb49c9166596dd78926514173b7f9ab5 ]

    Fix ip_defrag.sh when CONFIG_NF_DEFRAG_IPV6=m:

    $ sudo ./ip_defrag.sh
    + set -e
    + mktemp -u XXXXXX
    + readonly NETNS=ns-rGlXcw
    + trap cleanup EXIT
    + setup
    + ip netns add ns-rGlXcw
    + ip -netns ns-rGlXcw link set lo up
    + ip netns exec ns-rGlXcw sysctl -w net.ipv4.ipfrag_high_thresh=9000000
    + ip netns exec ns-rGlXcw sysctl -w net.ipv4.ipfrag_low_thresh=7000000
    + ip netns exec ns-rGlXcw sysctl -w net.ipv4.ipfrag_time=1
    + ip netns exec ns-rGlXcw sysctl -w net.ipv6.ip6frag_high_thresh=9000000
    + ip netns exec ns-rGlXcw sysctl -w net.ipv6.ip6frag_low_thresh=7000000
    + ip netns exec ns-rGlXcw sysctl -w net.ipv6.ip6frag_time=1
    + ip netns exec ns-rGlXcw sysctl -w net.netfilter.nf_conntrack_frag6_high_thresh=9000000
    + cleanup
    + ip netns del ns-rGlXcw

    $ ls -la /proc/sys/net/netfilter/nf_conntrack_frag6_high_thresh
    ls: cannot access '/proc/sys/net/netfilter/nf_conntrack_frag6_high_thresh': No such file or directory

    $ sudo modprobe nf_defrag_ipv6
    $ ls -la /proc/sys/net/netfilter/nf_conntrack_frag6_high_thresh
    -rw-r--r-- 1 root root 0 Jul 14 12:34 /proc/sys/net/netfilter/nf_conntrack_frag6_high_thresh
