Subject: [PATCH 4.1 17/43] vxlan: fix incorrect RCO bit in VXLAN header

4.1-stable review patch.  If anyone has any objections, please let me know.

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

From: Jiri Benc <jbenc@...hat.com>

[ Upstream commit c5fb8caaf91ea6a92920cf24db10cfc94d58de0f ]

Commit 3511494ce2f3d ("vxlan: Group Policy extension") changed definition of
VXLAN_HF_RCO from 0x00200000 to BIT(24). This is obviously incorrect. It's
also in violation with the RFC draft.
