IB/mlx5: Replace tunnel mpls capability bits for tunnel_offloads

2020-04-13T11:18:05Z

commit 41e684ef3f37ce6e5eac3fb5b9c7c1853f4b0447 upstream. Until now the flex parser capability was used in ib_query_device() to indicate tunnel_offloads_caps support for mpls_over_gre/mpls_over_udp. Newer devices and firmware will have configurations with the flexparser but without mpls support. Testing for the flex parser capability was a mistake, the tunnel_stateless capability was intended for detecting mpls and was introduced at the same time as the flex parser capability. Otherwise userspace will be incorrectly informed that a future device supports MPLS when it does not.

net/mlx5: DR, Handle reformat capability over sw-steering tables

2020-02-19T03:01:20Z

On flow table creation, send the relevant flags according to what the FW currently supports. When FW doesn't support reformat option over SW-steering managed table, the driver shouldn't pass this.

IB/mlx5: Return the administrative GUID if exists

2020-01-25T18:54:39Z

A user can change the operational GUID (a.k.a affective GUID) through link/infiniband. Therefore it is preferred to return the currently set GUID if it exists instead of the operational. This way the PF can query which VF GUID will be set in the next bind. In order to align with MAC address, zero is returned if administrative GUID is not set. For example, before setting administrative GUID: $ ip link show ib0: mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 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 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 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 00:00:00:00:00:00:00:00, PORT_GUID 00:00:00:00:00:00:00:00, link-state auto, trust off, query_rss off Then: $ ip link set ib0 vf 0 node_guid 11:00:af:21:cb:05:11:00 $ ip link set ib0 vf 0 port_guid 22:11:af:21:cb:05:11:00 After setting administrative GUID: $ ip link show ib0: mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 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 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 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 11:00:af:21:cb:05:11:00, PORT_GUID 22:11:af:21:cb:05:11:00, link-state auto, trust off, query_rss off Fixes: 9c0015ef0928 ("IB/mlx5: Implement callbacks for getting VFs GUID attributes") Link: https://lore.kernel.org/r/20200116120048.12744-1-leon@kernel.org Signed-off-by: Danit Goldberg Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

net/mlx5: Allow creating autogroups with reserved entries

2020-01-16T23:48:58Z

Exclude the last n entries for an autogrouped flow table. Reserving entries at the end of the FT will ensure that this FG will be the last to be evaluated. This will be used in the next patch to create a miss group enabling custom actions on FT miss.

net/mlx5: Add ignore level support fwd to table rules

2020-01-16T23:48:58Z

If user sets ignore flow level flag on a rule, that rule can point to a flow table of any level, including those with levels equal or less than the level of the flow table it is added on. This with unamanged tables will be used to create a FDB chain/prio hierarchy much larger than currently supported level range.

net/mlx5: fs_core: Introduce unmanaged flow tables

2020-01-16T23:48:58Z

Currently, Most of the steering tree is statically declared ahead of time, with steering prios instances allocated for each fdb chain to assign max number of levels for each of them. This allows fs_core to manage the connections and levels of the flow tables hierarcy to prevent loops, but restricts us with the number of supported chains and priorities. Introduce unmananged flow tables, allowing the user to manage the flow table connections. A unamanged table is detached from the fs_core flow table hierarcy, and is only connected back to the hierarchy by explicit FTEs forward actions. This will be used together with firmware that supports ignoring the flow table levels to increase the number of supported chains and prios.
