The driver still was not offloading TSO on GRE tunnels because it forgot to set the GSO_GRE flag, causing lots of retransmits. This fixes generic GRE traffic (like a tunnel added like below) whereas before it would get 1Gb/s or less, now on a 10G adapter it gets 8.7Gb/s. ip ad ad 11.1.0.2/24 dev ens2f0 ip l set ens2f0 up ip link add gre2 type gretap remote 11.1.0.1 local 11.1.0.2 dev ens2f0 ip l set gre2 up ip ad ad 192.168.124.2/24 dev gre2 ping 192.168.124.1 netperf -H 192.168.124.1 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> --- drivers/net/ethernet/intel/i40e/i40e_main.c | 2 ++ 1 file changed, 2 insertions(+)
