Hi netdev! I'm kernel newbie and I'm not sure it's right place to ask though, if not please let me know the right place. :)
I sent this mail to ask about net_device interface feature called 'tx-udp_tnl-segmentation'. Ethtool does not appear correct status of offloading, even if the vxlan offloading is enabled. Ethtool show like below for vxlan interface. deploy@krane-pg1-com1000:~$ ethtool --show-offload vxlan100 Features for vxlan100: tx-udp_tnl-segmentation: off [fixed] deploy@krane-pg1-com1000:~$ ethtool --show-offload eth0 Features for eth0: tx-udp_tnl-csum-segmentation: on Tcpdumping show offload is correctly applied in vxlan interface, so I wonder this is bug for vxlan implementation. I found drivers/net/vxlan.c does not set the feature SKB_GSO_UDP_TUNNEL, just applying the flag at creation time. Is it bug or something that I misunderstood? Thanks in advance! Best regards Yang Youseok
