Subject[77/82] xfrm4: strip ECN bits from tos field
2.6.35-stable review patch.  If anyone has any objections, please let us know.

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


From: Ulrich Weber <uweber@astaro.com>

[ Upstream commit 94e2238969e89f5112297ad2a00103089dde7e8f ]

otherwise ECT(1) bit will get interpreted as RTO_ONLINK
and routing will fail with XfrmOutBundleGenError.
