Subject: net: unset IFF_XMIT_DST_RELEASE in ipgre_tunnel_setup()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=108bfa895cacd1a7c1767e85be105b213e5dce50;p=openwrt%2Fstaging%2Fblogic.git

net: unset IFF_XMIT_DST_RELEASE in ipgre_tunnel_setup()

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