4 years agoice: Implement aRFS
Brett Creeley [Tue, 12 May 2020 01:01:46 +0000 (18:01 -0700)]
ice: Implement aRFS

Enable accelerated Receive Flow Steering (aRFS). It is used to steer Rx
flows to a specific queue. This functionality is triggered by the network
stack through ndo_rx_flow_steer and requires Flow Director (ntuple on) to
function.

The fltr_info is used to add/remove/update flow rules in the HW, the
fltr_state is used to determine what to do with the filter with respect
to HW and/or SW, and the flow_id is used in co-ordination with the
network stack.

The work for aRFS is split into two paths: the ndo_rx_flow_steer
operation and the ice_service_task. The former is where the kernel hands
us an Rx SKB among other items to setup aRFS and the latter is where
the driver adds/updates/removes filter rules from HW and updates filter
state.

In the Rx path the following things can happen:
        1. New aRFS entries are added to the hash table and the state is
           set to ICE_ARFS_INACTIVE so the filter can be updated in HW
           by the ice_service_task path.
        2. aRFS entries have their Rx Queue updated if we receive a
           pre-existing flow_id and the filter state is ICE_ARFS_ACTIVE.
           The state is set to ICE_ARFS_INACTIVE so the filter can be
           updated in HW by the ice_service_task path.
        3. aRFS entries marked as ICE_ARFS_TODEL are deleted

In the ice_service_task path the following things can happen:
        1. New aRFS entries marked as ICE_ARFS_INACTIVE are added or
           updated in HW.
           and their state is updated to ICE_ARFS_ACTIVE.
        2. aRFS entries are deleted from HW and their state is updated
           to ICE_ARFS_TODEL.

ice: Don't reset and rebuild for Tx timeout on PFC enabled queue

When there's a Tx timeout for a queue which belongs to a PFC enabled TC,
then it's not because the queue is hung but because PFC is in action.

In PFC, peer sends a pause frame for a specified period of time when its
buffer threshold is exceeded (due to congestion). Netdev on the other

ice: Add VF promiscuous support

Implement promiscuous support for VF VSIs. Behaviour of promiscuous support
is based on VF trust as well as the, introduced, vf-true-promisc flag.

A trusted VF with vf-true-promisc disabled will be the default VSI, which
means that all traffic without a matching destination MAC address in the
device's internal switch will be forwarded to this VF VSI.

A trusted VF with vf-true-promisc enabled will go into "true promiscuous
mode". This amounts to the VF receiving all ingress and egress traffic
that hits the device's internal switch.

An untrusted VF will only receive traffic destined for that VF.

The vf-true-promisc-support flag cannot be toggled while any VF is in
promiscuous mode. This flag should be set prior to loading the iavf driver
or spawning VF(s).

igc: Refactor ethertype filtering code

The whole ethertype filtering code is implemented in igc_ethtool.c and
mixes logic from ethtool and core parts. This patch refactors it so core
logic is moved to igc_main.c, aligning the ethertype filtering code
organization with the rest of the filtering code from the driver (MAC
address and VLAN priority).

Besides moving code to igc_main.c, this patch also does some minor
improvements to the code. Below are some highlights.

In case all filters are already in use and the user tries to add another
filter, we return -ENOSPC instead of -EINVAL so a more meaningful error
code is provided. This also aligns with the behavior implemented in MAC
address filtering code.

With this code refactoring, 'etype_bitmap' array in struct igc_adapter
and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore
and are removed.

Log messages are added to help debugging the ethertype filtering code.

====================
add a new ->ndo_tunnel_ctl method to avoid a few set_fs calls v2

a tunnel using code that doesn't live in the core kernel or ipv6 module.
Currently they call ioctls on the tunnel devices to create these, for
which the code needs to override the address limit, which is a "feature"

Instead this patchset adds a new ->ndo_tunnel_ctl that can be used for
the tunnel configuration using struct ip_tunnel_parm.  The method is
either invoked from a helper that does the uaccess and can be wired up

1GbE Intel Wired LAN Driver Updates 2020-05-18

This series contains updates to igc driver only.

Sasha adds ECN support for TSO by adding the NETIF_F_TSO_ECN flag, which
aligns with other Intel drivers.  Also cleaned up defines that are not
supported or used in the igc driver.

Andre does most of the changes with updating the log messages for igc
driver.

Vitaly adds support for EEPROM, register and link ethtool
self-tests.

v2: Fixed up the added ethtool self-tests based on feedback from the
    community.  Dropped the four patches that removed '\n' from log
    messages.
v3: Reverted the debug message changes in patch 2 for messages in
    igc_probe, also made reg_test[] static in patch 3 based on community
    feedback
v4: Updated the patch description for patch 2, which referred to changes
    that no longer existed in the patch

4 years agor8169: work around an irq coalescing related tx timeout

r8169: work around an irq coalescing related tx timeout

In [0] a user reported reproducible tx timeouts on RTL8168f except
PktCntrDisable is set and irq coalescing is enabled.
Realtek told me that they are not aware of any related hw issue on
this chip version, therefore root cause is still unknown. It's not
clear whether the issue affects one or more chip versions in general,
or whether issue is specific to reporter's system.
Due to this level of uncertainty, and due to the fact that I'm aware
of this one report only, let's apply the workaround on net-next only.
After this change setting irq coalescing via ethtool can reliably
avoid the issue on the affected system.
