So I have an interface eth0. On that, I created a virtual network interface if-vx (vxlan) using ip link add command. When I use ethtool -K eth0 tx off, I receive the set of features active on eth0 via __netdev_update_features() callback calling ndo_set_features() in my driver.
However, when I do the same on virtual interface (vxlan), ethtool -K if-vx tx off, I do not see a call to ndo_set_features() so my driver does not get to know if the feature is on or off. Any idea on how to retrieve the active feature bits on vxlan interface?
Thanks for the reply. Shouldn't there be any API to send relevant information (offload information) to the driver running on eth0 interface as it acts as vtep?
For example, If I disable rx checksum offload on vxlan interface (ethtool -K if-vx rx off), it means rx checksum verification should not be performed by the hardware and guest will do it. However, my driver does not get to know this offload setting change on vxlan interface.
Is there any way I can retrieve this information? These two interface should be linked somehow I guess?
