2017-06-27IB/mlx5: Respect mlx5_core reserved GIDsIlan Tayari1-66/+53
Reserved gids are taken by the mlx5_core, report smaller GID table size to IB core. Set mlx5_query_roce_port's return value back to int. In case of error, return an indication. This rolls back some of the change in commit 50f22fd8ecf9 ("IB/mlx5: Set mlx5_query_roce_port's return value to void") Change set_roce_addr to use gid_set function, instead of directly sending the command.

2017-04-21IB/mlx5: Set correct SL in completion for RoCEMoni Shoua1-3/+16
There is a difference when parsing a completion entry between Ethernet and IB ports. When link layer is Ethernet the bits describe the type of L3 header in the packet. In the case when link layer is Ethernet and VLAN header is present the value of SL is equal to the 3 UP bits in the VLAN header. If VLAN header is not present then the SL is undefined and consumer of the completion should check if IB_WC_WITH_VLAN is set. While that, this patch also fills the vlan_id field in the completion if present.

2017-04-21IB/mlx5: Use IP version matching to classify IP trafficAriel Levkovich1-17/+49
This change adds the ability for flow steering to classify IPv4/6 packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP packets and hit IPv4/6 classifed steering rules. When user added a flow rule with IP classification, driver was implicitly adding ethertype matching to the created rule in order to distinguish between IPv4 and IPv6 protocols. Since IP packets with MPLS tag header have MPLS ethertype, they missed the rule and ended up hitting the default filters. Such behavior prevented from MPLS packets to undergo inbound traffic load balancing flows (if such were defined by configuring RSS) to achieve higher throughput - the way that non-MPLS IP packets performed. Since our device is able to look past the MPLS tag and identify the next protocol we introduce this solution which replaces Ethertype matching by the device's capability to perform IP version parsing and matching in order to distinguish between IPv4 and IPv6. Therefore, whenever a flow with IP spec is added and device support IP version matching, driver will implicitly add IP version matching to the rule (Based on the IP spec type) without Ethertype matching which will cause relevant MPLS tagged packets to hit this rule as well. Otherwise (device doesn't support IP version matching), we fall back to setting Ethertype matching. If the user's filters specify an L2 ethertype and an IP spec the rule will then match both the ethertype and the IP version. The device's support for IP version matching is reported by the device via dedicated capability bit in query_device_cap and named outer/inner_ip_version.

2017-04-21IB/mlx5: Add inner spec and IPv6 validation in user's flow attribute listAriel Levkovich1-10/+34
This change fixes an incomplete validation of the user's flow attributes list. Previous implementation validated only matching of IPv4 Ethertype to IPv4 spec of outer headers (in case both Ethernet with specified Ethertype and IP specs were present) and lacked the validation of: 1. Matching of IPv6 Ethertype in Ethernet spec (if such exists) to an IPv6 protocol spec (if such exists). 2. Validation of Ethertype to IP protocol matching on inner headers specs. Which could cause some combinations of unmatching Ethernet and IP protocols to pass validation and apply on the device. The fix adds validation of IPv6 Ethertype and IP spec as well as performing the scan on both outer and inner attributes.

2017-02-15IB/mlx5: Fix configuration of port capabilitiesEli Cohen1-0/+35
When the "ib_virt" cap is set, configuration of port capabilities need to be done through mlx5_core_modify_hca_vport_context. Since modify_hca_vport_context accepts mask and value, there is no need to read the port capabilities and calculate the new cap values so we avoid the mutex when ib_virt is set.

2017-02-14IB: Query ports via the core instead of direct into the driverOr Gerlitz2-5/+8
Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers. This patch doesn't add any new functionality.
