Hi Alexander,
Thank you very much for all your explanation about vlan and UDP tunnel TSO
support, I have checked 4.7+ kernel again, it turns out I misunderstand
vlan_dev_fix_features, it just use vlan_features&features of real device to
check HW_CSUM support, and does not even care about GSO_UDP_T

As far as I know t
Hi Alexander,
Thanks a lot for your reply, the following code is excerpted from function
ixgbe_probe in ixgbe_main.c of 4.1.5 driver code.
#ifdef HAVE_ENCAP_TSO_OFFLOAD
netdev->features |= NETIF_F_GSO_UDP_TUNNEL;
#endif
As you can see, its controlled by a macro which will be defined with 3.10+

Hi,
I am now research on VXLAN OFFLOAD of intel 82599 NIC with openvswitch
2.6.0, after reading some code and does the test, and I have concluded it
seems if the VXLAN endpoint ip is configured on a vlan interface like
eth0.100, VXLAN OFFLOAD will not work, while eth0 itself is 82599 NIC which
