bonding: handle more gso types
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. ethtool -K bond0 tx-gre-segmentation off super_netperf 50 --google-pacing-rate 30000000 -H 10.7.8.152 -l 15 7538.32 ethtool -K bond0 tx-gre-segmentation on super_netperf 50 --google-pacing-rate 30000000 -H 10.7.8.152 -l 15 10200.5 Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.
