 tagger Saeed Mahameed <saeedm@mellanox.com> 1504133679 +0300
 
 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)
 
 Thanks,
 Saeed.
