In commit 5a7baa78851b ("bonding: Advertize vxlan offload features when
supported"), Or Gerlitz added support conditional vxlan offload.
In this patch I also add support for all kind of tunnels,
but we allow a bonding device to not require segmentation,
as it is always better to make this segmentation at the very last stage,
if a particular slave device requires it.
Tested:
Setup a GRE tunnel,
on a physical NIC not having tx-gre-segmentation.
Results on bnx2x are even better, as we no longer have to segment
in software.
