Merge tag 'mlx5-GRE-Offload' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux
Saeed Mahameed says: ==================== mlx5-updates-2017-08-31 (GRE Offloads support) This series provides the support for MPLS RSS and GRE TX offloads and RSS support. The first patch from Gal and Ariel provides the mlx5 driver support for ConnectX capability to perform IP version identification and matching in order to distinguish between IPv4 and IPv6 without the need to specify the encapsulation type, thus perform RSS in MPLS automatically without specifying MPLS ethertyoe. This patch will also serve for inner GRE IPv4/6 classification for inner GRE RSS. 2nd patch from Gal, Adds the TX offloads support for GRE tunneled packets, by reporting the needed netdev features. 3rd patch from Gal, Adds GRE inner RSS support by creating the needed device resources (Steering Tables/rules and traffic classifiers) to Match GRE traffic and perform RSS hashing on the inner headers. Improvement: Testing 8 TCP streams bandwidth over GRE: System: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz NIC: Mellanox Technologies MT28800 Family [ConnectX-5 Ex] Before: 21.3 Gbps (Single RQ) Now : 90.5 Gbps (RSS spread on 8 RQs) ==================== Signed-off-by: David S.
