drivers/net/vxlan.c: In function ‘vxlan_newlink’:
include/net/vxlan.h:30:28: error: ‘VXLAN_F_UDP_ZERO_CSUM6_RX’ undeclared (first
use in this function)
  #define VXLAN_F_RCV_FLAGS  VXLAN_F_UDP_ZERO_CSUM6_RX

Culprit is 'vxlan: fix test which detect duplicate vxlan iface'.
VXLAN_F_UDP_ZERO_CSUM6_RX
does not exist in v3.14. Copying Nicolas Dichtel for advice.
The "Fixes" tag in the original patch indicates that the bug was introduced by
commit 1c51a9159dde ("vxlan: fix race caused by dropping rtnl_unlock"), ie in
linux 3.11.
I don't see a backport of this patch in the 3.10 branch, so I think that we
can drop this patch for the 3.10 branch.

About the 3.14 branch: VXLAN_F_UDP_ZERO_CSUM6_RX has been introduce in 3.16 by
commit 359a0ea9875e ("vxlan: Add support for UDP checksums (v4 sending, v6 zero
csums)").
I think that we can just drop the test against the flags.


Regards,
Nicolas
