net/mlx5e: TX, Add geneve tunnel stateless offload support
Currently support only default geneve udp port (6081). For the tx side, the HW is assisted by SW parsing, which sets the headers offset to offload tunneled LSO and csum. Note that for udp tunnels, we don't use special rx offloads, as rss on the outer headers is enough, we support checksum complete and GRO takes care of aggregation. Geneve TSO BW and CPU load results (tested using iperf single tcp stream). In this patch we add TSO support over Geneve, so the "before" result doesn't actually get to using the TSO HW offload even when turned on. Tested on ConnectX-5, Intel(R) Xeon(R) CPU E5-2660 v2 @2.20GHz. __________________________________ | Before | After | |________________|_________________| | 12.6 Gbits/sec | 21.7 Gbits/sec | | 100% CPU load | 61.5% CPU load | |________________|_________________| Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Acked-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
