2019-07-01net/mlx5: Handle host PF vport mac/guid for ECPFBodong Wang8-17/+25
When ECPF is eswitch manager, it has the privilege to query and configure the mac and node guid of host PF. While vport number of host PF is 0, the vport command should be issued with other_vport set in this case as the cmd is issued by ECPF vport(0xfffe). Add a specific function to query own vport mac. Low level functions are used by vport manager to query/modify any vport mac and node guid. Signed-off-by: Bodong Wang <bodong@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2019-07-01net/mlx5: Don't handle VF func change if host PF is disabledBodong Wang1-1/+4
When ECPF eswitch manager is at offloads mode, it monitors functions changed event from host PF side and acts according to the number of VFs enabled/disabled. As ECPF and host PF work in two independent hosts, it's possible that host PF OS reboots but ECPF system is still kept on and continues monitoring events from host PF. When kernel from host PF side is booting, PCI iov driver does sriov_init and compute_max_vf_buses by iterating over all valid num of VFs. This triggers FLR and generates functions changed events, even though host PF HCA is not enabled at this time. However, ECPF is not aware of this information, and still handles these events as usual. ECPF system will see massive number of reps are created, but destroyed immediately once creation finished. To eliminate this noise, a bit is added to host parameter context to indicate host PF is disabled. ECPF will not handle the VF changed event if this bit is set.

In vport metadata matching, source port number is replaced by metadata. While FW has no idea about what it is in the metadata, a syndrome will happen. Specify a known origin to avoid the syndrome. However, there is no functional change because ANY_VPORT (0) is filled in flow_source, the same default value as before, as a pre-step towards metadata matching for fast path. There are two other values can be filled in flow_source. When setting 0x1, packet matching this rule is from uplink, while 0x2 is for packet from other local vports.

2019-06-26net/mlx5: E-Switch, Tag packet with vport number in VF vports and uplink ↵Jianbo Liu3-36/+155
ingress ACLs When a dual-port VHCA sends a RoCE packet on its non-native port, and the packet arrives to its affiliated vport FDB, a mismatch might occur on the rules that match the packet source vport as it is not represented by single VHCA only in this case. So we change to match on metadata instead of source vport. To do that, a rule is created in all vports and uplink ingress ACLs, to save the source vport number and vhca id in the packet's metadata in order to match on it later. The metadata register used is the first of the 32-bit type C registers. It can be used for matching and header modify operations. The higher 16 bits of this register are for vhca id, and the lower 16 ones is for vport number. This change is not for dual-port RoCE only. If HW and FW allow, the vport metadata matching is enabled by default.

2019-05-31net/mlx5: Introduce termination table bitsEli Britstein1-0/+3
Termination table is a flow table with a termination flag. The flag allows the firmware to assume that the the specified actions are the last actions list. This assumption allows the FW to safely perform potential looping logic (e.g. hairpin). Introduce the bits for this attribute.

2019-05-28net/mlx5: potential error pointer dereference in error handlingDan Carpenter1-2/+2
The error handling was a bit flipped around. If the mlx5_create_flow_group() function failed then it would have resulted in dereferencing "fg" when it was an error pointer.
