net/mlx5: Add MLX5_ARRAY_SET64 to fix BUILD_BUG_ON

2016-10-13T14:13:24+00:00

I am hitting this in mlx5:

drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c: In function
reclaim_pages_cmd.clone.0:
drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c:346: error: call
to __compiletime_assert_346 declared with attribute error:
BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_out, pas[i]) % 64
drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c: In function give_pages:
drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c:291: error: call
to __compiletime_assert_291 declared with attribute error:
BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_in, pas[i]) % 64

Problem is that this is doing a BUILD_BUG_ON on a non-constant
expression because of trying to take offset of pas[i] in the
structure.

Fix is to create MLX5_ARRAY_SET64 that takes an additional argument
that is the field index to separate between BUILD_BUG_ON on the array
constant field and the indexed field to assign the value to.
There are two callers of MLX5_SET64 that are trying to get a variable
offset, change those to call MLX5_ARRAY_SET64 passing 'pas' and 'i'
as the arguments to use in the offset check and the indexed value
assignment.

net/mlx5: Introduce attach/detach to interface API

2016-09-11T04:21:49+00:00

Add attach/detach callbacks to interface API.
This is crucial for implementing seamless reset flow which releases the
hardware and it's resources upon detach while keeping software
structures and state (e.g netdev) then reset and reallocate the hardware
needed resources upon attach.

net/mlx5: SRIOV core code refactoring

2016-09-11T04:21:49+00:00

Simplify the code and makes it look modular and symmetric.
Split sriov enable/disable to two levels: device level and pci level.
When user enable/disable sriov (via sriov_configure driver callback) we
will enable/disable both device and pci sriov.
When driver load/unload we will enable/disable (on demand) only device
sriov while keeping the PCI sriov enabled for next driver load.
On internal/pci error, VFs will be kept enabled on PCI and the reset
is done only in device level.

net/mlx5e: Move an_disable_cap bit to a new position

2016-09-08T23:15:28+00:00

Previous an_disable_cap position bit31 is deprecated to be use in driver
with newer firmware.  New firmware will advertise the same capability
in bit29.

Old capability didn't allow setting more than one protocol for a
specific speed when autoneg is off, while newer firmware will allow
this and it is indicated in the new capability location.

net/mlx5: Add sniffer namespaces

2016-08-18T15:49:59+00:00

Add sniffer TX and RX namespaces to receive ingoing and outgoing
traffic.

Each outgoing/incoming packet is duplicated and steered to the sniffer
TX/RX namespace in addition to the regular flow.

net/mlx5: Introduce sniffer steering hardware capabilities

2016-08-18T15:49:59+00:00

Define needed hardware capabilities for sniffer
RX and TX flow tables.

Add the following capabilities:
1. Sniffer RX flow table capabilities.
2. Sniffer TX flow table capabilities.
3. If same TIR can be used by multiple flow tables of different types.

net/mlx5: Add LAG flow steering namespace

2016-08-18T15:49:57+00:00

This namespace is used for LAG demux flowtable.

The idea is to position the LAG demux ft between
bypass and kernel flowtables, allowing raw-eth
traffic from both ports to be received by the PF0
IB device.

net/mlx5: LAG demux flow table support

2016-08-18T15:49:56+00:00

Add interfaces to allow the creation and destruction of a
LAG demux flow table.

It is a special flow table used during LAG for redirecting
non user-mode packets from PF0 to PF1 root ft, if a packet was
received on phys port two.
