mlxsw: spectrum_trap: Prepare policers for registration with devlink · 4561705b

由 Ido Schimmel 提交于 3月 30, 2020

Prepare an array of policer IDs to register with devlink and their
associated parameters.

The array is composed from both policers that are currently bound to
exposed trap groups and policers that are not bound to any trap group.

v2:
* Provide max/min rate/burst size when registering policers

mlxsw: spectrum: Track used packet trap policer IDs · 03484e49

由 Ido Schimmel 提交于 3月 30, 2020

During initialization the driver configures various packet trap groups
and binds policers to them.

Currently, most of these groups are not exposed to user space and
therefore their policers should not be exposed as well. Otherwise, user
space will be able to alter policer parameters without knowing which
packet traps are policed by the policer.

Use a bitmap to track the used policer IDs so that these policers will
not be registered with devlink in a subsequent patch.

mlxsw: reg: Extend QPCR register · 2b84d7c3

由 Ido Schimmel 提交于 3月 30, 2020

The QoS Policer Configuration Register (QPCR) is used to configure
hardware policers. Extend this register with following fields and
defines which will be used by subsequent patches:

1. Violate counter: reads number of packets dropped by the policer
2. Clear counter: to ensure we start counting from 0
3. Rate and burst size limits

devlink: Add packet trap group parameters support · f9f54392

由 Ido Schimmel 提交于 3月 30, 2020

Packet trap groups are used to aggregate logically related packet traps.
Currently, these groups allow user space to batch operations such as
setting the trap action of all member traps.

In order to prevent the CPU from being overwhelmed by too many trapped
packets, it is desirable to bind a packet trap policer to these groups.
For example, to limit all the packets that encountered an exception
during routing to 10Kpps.

Allow device drivers to bind default packet trap policers to packet trap
groups when the latter are registered with devlink.

The next patch will enable user space to change this default binding.

mlxsw: spectrum_ptp: Fix build warnings · ea315c55

由 Ido Schimmel 提交于 3月 30, 2020

Cited commit extended the enums 'hwtstamp_tx_types' and
'hwtstamp_rx_filters' with values that were not accounted for in the
switch statements, resulting in the build warnings below.

Fix by adding a default case.

drivers/net/ethernet/mellanox/mlxsw/spectrum_ptp.c: In function ‘mlxsw_sp_ptp_get_message_types’:
