Subject: net: unset IFF_XMIT_DST_RELEASE in ipip_tunnel_setup()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=28e72216d7e7af7050f171a87c1eecba93d01ea6;p=openwrt%2Fstaging%2Fblogic.git

net: unset IFF_XMIT_DST_RELEASE in ipip_tunnel_setup()

ipip_tunnel_xmit() might need skb->dst, so tell dev_hard_start_xmit()
to no release it.
