Subject: [GRE]: Use proper net in routing calls.
X-Git-Tag: v2.6.26-rc1~1138^2~40
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=96635522f7930025b8a56a7075db82c48a454a30;p=profile%2Fivi%2Fkernel-x86-ivi.git

[GRE]: Use proper net in routing calls.

As for the IPIP tunnel, there are some ip_route_output_key()
calls in there that require a proper net so give one to them.

And a proper net for the __get_dev_by_index hanging around.
