    Subject[PATCH 4.4 081/131] ipv6: fix endianness error in icmpv6_err
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    [ Upstream commit dcb94b88c09ce82a80e188d49bcffdc83ba215a6 ]

    IPv6 ping socket error handler doesn't correctly convert the new 32 bit
    mtu to host endianness before using.

    Cc: Lorenzo Colitti <lorenzo@google.com>
    Fixes: 6d0bfe22611602f ("net: ipv6: Add IPv6 support to the ping socket.")
