    Subject[PATCH 3.14 005/203] vxlan: fix a free after use
    Date
    3.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Li RongQing <roy.qing.li@gmail.com>

    [ Upstream commit 7a9f526fc3ee49b6034af2f243676ee0a27dcaa8 ]

    pskb_may_pull maybe change skb->data and make eth pointer oboslete,
    so eth needs to reload

    Fixes: 91269e390d062 ("vxlan: using pskb_may_pull as early as possible")
