      net/mlx5_core: Introduce forward to next priority action · b3638e1a
      由 Maor Gottlieb 提交于 
      Add support to create flow rule that forward packets
to the first flow table in the next priority (next priority
could be the first priority in the next namespace or the
next priority in the same namespace).
This feature could be used for DONT_TRAP rules or rules
that only want to mark the packet with flow tag.

In order to do it optimally, each flow table has list
of all rules that point to this flow table,
when a flow table is destroyed/created, we update the list
head correspondingly.

This kind of rule is created when destination is NULL and
action is MLX5_FLOW_CONTEXT_ACTION_FWD_NEXT_PRIO.

      net/mlx5: Use offset based reserved field names in the IFC header file · b4ff3a36
      由 Matan Barak 提交于 
      mlx5_ifc.h is a header file representing the API and ABI between
the driver to the firmware and hardware. This file is used from
both the mlx5_ib and mlx5_core drivers.

Previously, this file used incrementing counter to indicate
reserved fields, for example:

struct mlx5_ifc_odp_per_transport_service_cap_bits {
        u8         send[0x1];
        u8         receive[0x1];
        u8         write[0x1];
        u8         read[0x1];
        u8         reserved_0[0x1];
        u8         srq_receive[0x1];
        u8         reserved_1[0x1a];
};

If one developer implements through net-next feature A that uses
reserved_0, they replace it with featureA and renames reserved_1 to
reserved_0. In the same kernel cycle, a 2nd developer could implement
feature B through the rdma tree, that uses reserved_1 and split it to
featureB and a smaller reserved_1 field. This will cause a conflict
when the two trees are merged.

The source of this conflict is that the 1st developer changed *all*
reserved fields.

As Linus suggested, we change the layout of structs to:

struct mlx5_ifc_odp_per_transport_service_cap_bits {
	u8         send[0x1];
	u8         receive[0x1];
	u8         write[0x1];
	u8         read[0x1];
	u8         reserved_at_4[0x1];
	u8         srq_receive[0x1];
	u8         reserved_at_6[0x1a];
};

This makes the conflicts much more rare and preserves the locality of
changes.

      net/mlx5e: Added self loopback prevention · 66189961
      由 Tariq Toukan 提交于 
      Prevent outgoing multicast frames from looping back to the RX queue.

By introducing new HW capability self_lb_en_modifiable, which indicates
the support to modify self_lb_en bit in modify_tir command.

When this capability is set we can prevent TIRs from sending back
loopback multicast traffic to their own RQs, by "refreshing TIRs" with
modify_tir command, on every time new channels (SQs/RQs) are created at
device open.
This is needed since TIRs are static and only allocated once on driver
load, and the loopback decision is under their responsibility.

Fixes issues of the kind:
"IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!"
The issue is seen since the IPv6 solicitations multicast messages are
loopedback and the network stack thinks they are coming from another host.
