This causes a significant performance drop if the packets are later retransmitted. Fixing this revealed two other bugs which are also addressed as prerequisites: * GRO can aggregate packets for multiple layers of encapsulation which the stack cannot properly handle. * IPIP packets which are combined by GRO are not marked properly with their GSO type. Note that this is based off the net-next tree as the current target for bug fixes. v2: No code changes, just additional information in commit messages and a new cover letter. Jesse Gross (3): ipip: Properly mark ipip GRO packets as encapsulated. tunnels: Don't apply GRO to multiple layers of encapsulation. tunnels: Remove encapsulation offloads on decap. include/linux/netdevice.h | 4 ++-- include/net/ip_tunnels.h | 16 ++++++++++++++++ net/core/dev.c | 2 +- net/ipv4/af_inet.c | 24 ++++++++++++++++++++++-- net/ipv4/fou.c | 13 +++++++++++-- net/ipv4/gre_offload.c | 5 +++++ net/ipv4/ip_tunnel_core.c | 3 ++- net/ipv4/udp_offload.c | 6 +++--- net/ipv6/ip6_offload.c | 15 ++++++++++++++- net/ipv6/sit.c | 6 ++++-- 10 files changed, 80 insertions(+), 14 deletions(-) -- 2.5.0
