parentRDMA/qedr: Fix null-pointer dereference when calling rdma_user_mmap_get_offset (diff)
parentIB/mlx5: Implement callbacks for getting VFs GUID attributes (diff)
Merge branch 'ib-guids' into rdma.git for-next
Danit Goldberg says: ==================== This series extends RTNETLINK to provide IB port and node GUIDs, which were configured for Infiniband VFs. The functionality to set VF GUIDs already existed for a long time, and here we are adding the missing "get" so that netlink will be symmetric and various cloud orchestration tools will be able to manage such VFs more naturally. The iproute2 was extended too to present those GUIDs. - ip link show <device> For example: - ip link set ib4 vf 0 node_guid 22:44:33:00:33:11:00:33 - ip link set ib4 vf 0 port_guid 10:21:33:12:00:11:22:10 - ip link show ib4 ib4: <BROADCAST,MULTICAST> mtu 4092 qdisc noop state DOWN mode DEFAULT group default qlen 256 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 22:44:33:00:33:11:00:33, PORT_GUID 10:21:33:12:00:11:22:10, link-state disable, trust off, query_rss off ==================== Based on the mlx5-next branch from git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for dependencies * branch 'ib-guids': (35 commits) IB/mlx5: Implement callbacks for getting VFs GUID attributes IB/ipoib: Add ndo operation for getting VFs GUID attributes IB/core: Add interfaces to get VF node and port GUIDs net/core: Add support for getting VF GUIDs net/mlx5: Add new chain for netfilter flow table offload net/mlx5: Refactor creating fast path prio chains net/mlx5: Accumulate levels for chains prio namespaces net/mlx5: Define fdb tc levels per prio net/mlx5: Rename FDB_* tc related defines to FDB_TC_* defines net/mlx5: Simplify fdb chain and prio eswitch defines IB/mlx5: Load profile according to RoCE enablement state IB/mlx5: Rename profile and init methods net/mlx5: Handle "enable_roce" devlink param net/mlx5: Document flow_steering_mode devlink param devlink: Add new "enable_roce" generic device param net/mlx5: fix spelling mistake "metdata" -> "metadata" net/mlx5: fix kvfree of uninitialized pointer spec IB/mlx5: Introduce and use mlx5_core_is_vf() net/mlx5: E-switch, Enable metadata on own vport net/mlx5: Refactor ingress acl configuration ...
