The second patch goes through and enables IPv6 tunnel offloads for the Intel NICs that already support the IPv4 based IP-in-IP tunnel offloads. I have only done a bit of touch testing but have seen ~20 Gb/s over an i40e interface using a v4-in-v6 tunnel, and I have verified IPv6 GRE is still passing traffic at around the same rate. I plan to do further testing but with these patches present it should enable a wider audience to be able to test the new features introduced in Tom's patchset with hardware offloads. --- Alexander Duyck (2): ip6_gre: Do not allow segmentation offloads GRE_CSUM is enabled with FOU/GUE intel: Add support for IPv6 IP-in-IP offload drivers/net/ethernet/intel/i40e/i40e_main.c | 1 + drivers/net/ethernet/intel/i40e/i40e_txrx.c | 1 + drivers/net/ethernet/intel/i40evf/i40e_txrx.c | 1 + drivers/net/ethernet/intel/i40evf/i40evf_main.c | 1 + drivers/net/ethernet/intel/igb/igb_main.c | 1 + drivers/net/ethernet/intel/igbvf/netdev.c | 1 + drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 1 + drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c | 1 + net/ipv6/ip6_gre.c | 12 ++++++++---- 9 files changed, 16 insertions(+), 4 deletions(-)
