Some interfaces defined with unnecessary input parameters, such as "nent" and "vector". This patch redefined these interfaces to make the code more readable and simple. Link: https://lore.kernel.org/r/1574044493-46984-2-git-send-email-liweihang@hisilicon.comSigned-off-by:

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 ...

The cma is currently using a hard-coded value, CMA_IBOE_PACKET_LIFETIME, for the PacketLifeTime, as it can not be determined from the network. This value might not be optimal for all networks. The cma module supports the function rdma_set_ack_timeout to set the ACK timeout for a QP associated with a connection. As per IBTA 12.7.34 local ACK timeout = (2 * PacketLifeTime + Local CA’s ACK delay). Assuming a negligible local ACK delay, we can use PacketLifeTime = local ACK timeout/2 as a reasonable approximation for RoCE networks.

We cannot rely on the entry memcpy as we only copy the actual size of the command, the rest of the bytes must be memset to zero. Currently providing non-zero memory will not have any user visible impact.

Netfilter tables (nftables) implements a software datapath that comes after tc ingress datapath. The datapath supports offloading such rules via the flow table offload API. This API is currently only used by NFT and it doesn't provide the global priority in regards to tc offload, so we assume offloading such rules must come after tc. It does provide a flow table priority parameter, so we need to provide some supported priority range. For that, split fastpath prio to two, flow table offload and tc offload, with one dedicated priority chain for flow table offload. Next patch will re-use the multi chain API to access this chain by allowing access to this chain by the fdb_sub_namespace. Signed-off-by:

Next patch will re-use this to add a new chain but in a different prio. Signed-off-by:

Paul Blakey authored
Tc chains are implemented by creating a chained prio steering type, and inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each of those has a list of priorities. Currently, all namespaces in a prio start at the parent prio level. But since we can jump from chain (namespace) to another chain in the same prio, we need the levels for higher chains to be higher as well. So we created unused prios to account for levels in previous namespaces. Fix that by accumulating the namespaces levels if we are inside a chained type prio, and removing the unused prios.
