When setting speed to 100G via ethtool (AN is set to off), only 25G*4 is
configured while the user, who has an advanced HW which supports
extended PTYS, expects also 50G*2 to be configured.
With this patch, when extended PTYS mode is available, configure
PTYS via extended fields.

On some old Firmwares, connector type value was not supported, and value
read from FW was 0. For those, driver used link mode in order to set
connector type in link_ksetting.
After FW exposed the connector type, driver translated the value to ethtool
definitions. However, as 0 is a valid value, before returning PORT_OTHER,
driver run the check of link mode in order to maintain backward
compatibility.
Cited patch added support to EXT mode. With both features (connector type
and EXT link modes) ,if connector_type read from FW is 0 and EXT mode is
set, driver mistakenly compare EXT link modes to non-EXT link mode.
Fixed that by skipping this comparison if we are in EXT mode, as connector
type value is valid in this scenario.

Cited patch deleted ethtool flash device support, as ethtool core can
fallback into devlink flash callback. However, this is supported only if
there is a devlink port registered over the corresponding netdevice.
As mlx5e do not have devlink port support over native netdevice, it broke
the ability to flash device via ethtool.
This patch re-add the ethtool callback to avoid user functionality breakage
when trying to flash device via ethtool.

Speed translation is performed based on legacy or extended PTYS
register. Translate speed with respect to:
1) Capability bit of extended PTYS table.
2) User request:
a) When auto-negotiation is turned on, inspect advertisement whether it
contains extended link modes.
b) When auto-negotiation is turned off, speed > 100Gbps (maximal
speed supported in legacy mode).
With both conditions fulfilled translation is done with extended PTYS
table otherwise use legacy PTYS table.
Without this patch 25/50/100 Gbps speed cannot be set, since try to
configure in extended mode but read from legacy mode.

pull-request: bpf-next 2019-07-03
The following pull-request contains BPF updates for your *net-next* tree.
There is a minor merge conflict in mlx5 due to 8960b38932be ("linux/dim:
Rename externally used net_dim members") which has been pulled into your
tree in the meantime, but resolution seems not that bad ... getting current
bpf-next out now before there's coming more on mlx5. ;) I'm Cc'ing Saeed
just so he's aware of the resolution below:
** First conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:
<<<<<<< HEAD
static int mlx5e_open_cq(struct mlx5e_channel *c,
struct dim_cq_moder moder,
struct mlx5e_cq_param *param,
struct mlx5e_cq *cq)
=======
int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder,
struct mlx5e_cq_param *param, struct mlx5e_cq *cq)
>>>>>>> e5a3e259ef239f443951d401db10db7d426c9497
Resolution is to take the second chunk and rename net_dim_cq_moder into
dim_cq_moder. Also the signature for mlx5e_open_cq() in ...
drivers/net/ethernet/mellanox/mlx5/core/en.h +977
... and in mlx5e_open_xsk() ...
drivers/net/ethernet/mellanox/mlx5/core/en/xsk/setup.c +64
... needs the same rename from net_dim_cq_moder into dim_cq_moder.
** Second conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:
<<<<<<< HEAD
int cpu = cpumask_first(mlx5_comp_irq_get_affinity_mask(priv->mdev, ix));
struct dim_cq_moder icocq_moder = {0, 0};
struct net_device *netdev = priv->netdev;
struct mlx5e_channel *c;
unsigned int irq;
=======
struct net_dim_cq_moder icocq_moder = {0, 0};
>>>>>>> e5a3e259ef239f443951d401db10db7d426c9497
Take the second chunk and rename net_dim_cq_moder into dim_cq_moder
as well.
Let me know if you run into any issues. Anyway, the main changes are:
1) Long-awaited AF_XDP support for mlx5e driver, from Maxim.
2) Addition of two new per-cgroup BPF hooks for getsockopt and
setsockopt along with a new sockopt program type which allows more
fine-grained pass/reject settings for containers. Also add a sock_ops
callback that can be selectively enabled on a per-socket basis and is
executed for every RTT to help tracking TCP statistics, both features
from Stanislav.
3) Follow-up fix from loops in precision tracking which was not propagating
precision marks and as a result verifier assumed that some branches were
not taken and therefore wrongly removed as dead code, from Alexei.
4) Fix BPF cgroup release synchronization race which could lead to a
double-free if a leaf's cgroup_bpf object is released and a new BPF
program is attached to the one of ancestor cgroups in parallel, from Roman.
5) Support for bulking XDP_TX on veth devices which improves performance
in some cases by around 9%, from Toshiaki.
6) Allow for lookups into BPF devmap and improve feedback when calling into
bpf_redirect_map() as lookup is now performed right away in the helper
itself, from Toke.
7) Add support for fq's Earliest Departure Time to the Host Bandwidth
Manager (HBM) sample BPF program, from Lawrence.
8) Various cleanups and minor fixes all over the place from many others.

This commit adds support for AF_XDP zero-copy RX and TX.
We create a dedicated XSK RQ inside the channel, it means that two
RQs are running simultaneously: one for non-XSK traffic and the other
for XSK traffic. The regular and XSK RQs use a single ID namespace split
into two halves: the lower half is regular RQs, and the upper half is
XSK RQs. When any zero-copy AF_XDP socket is active, changing the number
of channels is not allowed, because it would break to mapping between
XSK RQ IDs and channels.
XSK requires different page allocation and release routines. Such
functions as mlx5e_{alloc,free}_rx_mpwqe and mlx5e_{get,put}_rx_frag are
generic enough to be used for both regular and XSK RQs, and they use the
mlx5e_page_{alloc,release} wrappers around the real allocation
functions. Function pointers are not used to avoid losing the
performance with retpolines. Wherever it's certain that the regular
(non-XSK) page release function should be used, it's called directly.
Only the stats that could be meaningful for XSK are exposed to the
userspace. Those that don't take part in the XSK flow are not
considered.
Note that we don't wait for WQEs on the XSK RQ (unlike the regular RQ),
because the newer xdpsock sample doesn't provide any Fill Ring entries
at the setup stage.
We create a dedicated XSK SQ in the channel. This separation has its
advantages:
1. When the UMEM is closed, the XSK SQ can also be closed and stop
receiving completions. If an existing SQ was used for XSK, it would
continue receiving completions for the packets of the closed socket. If
a new UMEM was opened at that point, it would start getting completions
that don't belong to it.
2. Calculating statistics separately.
When the userspace kicks the TX, the driver triggers a hardware
interrupt by posting a NOP to a dedicated XSK ICO (internal control
operations) SQ, in order to trigger NAPI on the right CPU core. This XSK
ICO SQ is protected by a spinlock, as the userspace application may kick
the TX from any core.
Store the pointers to the UMEMs in the net device private context,
independently from the kernel. This way the driver can distinguish
between the zero-copy and non-zero-copy UMEMs. The kernel function
xdp_get_umem_from_qid does not care about this difference, but the
driver is only interested in zero-copy UMEMs, particularly, on the
cleanup it determines whether to close the XSK RQ and SQ or not by
looking at the presence of the UMEM. Use state_lock to protect the
access to this area of UMEM pointers.
LRO isn't compatible with XDP, but there may be active UMEMs while
XDP is off. If this is the case, don't allow LRO to ensure XDP can
be reenabled at any time.
The validation of XSK parameters typically happens when XSK queues
open. However, when the interface is down or the XDP program isn't
set, it's still possible to have active AF_XDP sockets and even to
open new, but the XSK queues will be closed. To cover these cases,
perform the validation also in these flows:
1. A new UMEM is registered, but the XSK queues aren't going to be
created due to missing XDP program or interface being down.
2. MTU changes while there are UMEMs registered.
Having this early check prevents mlx5e_open_channels from failing
at a later stage, where recovery is impossible and the application
has no chance to handle the error, because it got the successful
return value for an MTU change or XSK open operation.
The performance testing was performed on a machine with the following
configuration:
- 24 cores of Intel Xeon E5-2620 v3 @ 2.40 GHz
- Mellanox ConnectX-5 Ex with 100 Gbit/s link
The results with retpoline disabled, single stream:
txonly: 33.3 Mpps (21.5 Mpps with queue and app pinned to the same CPU)

====================
Generic DIM
From: Tal Gilboa and Yamin Fridman
Implement net DIM over a generic DIM library, add RDMA DIM
dim.h lib exposes an implementation of the DIM algorithm for
dynamically-tuned interrupt moderation for networking interfaces.
We want a similar functionality for other protocols, which might need to
optimize interrupts differently. Main motivation here is DIM for NVMf
storage protocol.
Current DIM implementation prioritizes reducing interrupt overhead over
latency. Also, in order to reduce DIM's own overhead, the algorithm might
take some time to identify it needs to change profiles. While this is
acceptable for networking, it might not work well on other scenarios.
Here we propose a new structure to DIM. The idea is to allow a slightly
modified functionality without the risk of breaking Net DIM behavior for
netdev. We verified there are no degradations in current DIM behavior with
the modified solution.
Suggested solution:
- Common logic is implemented in lib/dim/dim.c
- Net DIM (existing) logic is implemented in lib/dim/net_dim.c, which uses
the common logic in dim.c
- Any new DIM logic will be implemented in "lib/dim/new_dim.c".
This new implementation will expose modified versions of profiles,
dim_step() and dim_decision().
- DIM API is declared in include/linux/dim.h for all implementations.
Pros for this solution are:
- Zero impact on existing net_dim implementation and usage
- Relatively more code reuse (compared to two separate solutions)
- Increased extensibility

Support Mellanox BlueField SmartNIC (mlx5-updates-2019-02-15)
Bodong Wang says,
BlueField device is a multi-core ARM processor in a highly integrated
system on chip coupled with the ConnectX interconnect controller.
BlueField device can be presented in one out of two modes:
- SEPARATED_HOST: ARM processors as a separated and orthogonal host
like any other external host in the multi-host virtualization model.
- EMBEDDED_CPU: ARM processors as Embedded CPU (EC) and part of the
external hosts virtualization model.
While existing driver already supports the device on separated_host
mode, this patch series focus on the functionalities of embedded_cpu
mode.
On embedded_cpu mode, BlueField device exposes regular network
controller PCI function in the BlueField host(e.g, x86). However, a
separate PCI function called Embedded CPU Physical Function(ECPF) is
also added to the ARM host side, where standard Linux distributions is
able to run on the ARM cores. Depends on the NV configuration from
firmware, ECPF can be the e-switch manager and firmware pages supplier.
If ECPF is configured as e-switch manager and page supplier, it will
take over the responsibilities from the PF on BlueField host includes:
- Owns, controls and manages all e-switch parts, and takes e-switch
traffic by default. It also should perform ENABLE_HCA for the host
PF just like a PF does for its VFs.
- Provides and manages the ICM host memory required for the HCA to
store various contexts for itself, the PF and VFs belong the
e-switch it manages.
The PF on BlueField host side is still responsible for:
- Control its own permanent MAC.
- PCI and SRIOV configurations and perform ENABLE_HCA for its VFs.
The ECPF can also retrieve information about the external host it
controls, like host identifier, PCI BDF and number of virtual functions.
As these parameters may be changed dynamically, an event will be triggered
to the driver on ECPF side.

New channels are applied to the priv channels only after they
are successfully opened. Then, the indirection table should be built
according to the new number of channels.
Currently, such build is preformed independently of whether the
channels opening is successful, and is not reverted on failure.
The bug is caused due to removal of rss params from channels struct
and moving it to priv struct. That change cause to independency between
channels and rss params.
This causes a crash on a later point, when accessing rqn of a non
existing channel.
This patch fixes it by moving the indirection table build right before
switching the priv channels to new channels struct, after the new set of
channels was successfully opened.

Move modify tirs hash functionality (mlx5e_modify_tirs_hash) from
en_ethtool.c to en_main.c. This allows future use of this fuctionality
from en_fs_ethtool.c, while keeping current convention: en_ethtool.c
doesn't have an API. There is no functional change here.

If FEC caps query fails when executing 'ethtool <interface>'
the whole callback fails unnecessarily, fixed that by replacing the
error return code with debug logging only.

Driver callback function for 'ethtool --show-fec',
'ethtool --set-fec' commands.
The query function returns active and configured FEC policy
for current link speed.
The set function sets FEC policy for all supported link
speeds.
1) If current link speed doesn't support requested FEC policy,
the function fails.
2) If a different link speed doesn't support requested FEC
policy, FEC capbilities for this speed are turned off.

The current design of mlx5e driver ignores the netdevice TX/RX queues
number for netdevices that RDMA IPoIB ULP creates. Instead, the queue
number is initialized to the maximum number that mlx5 thinks best for
performance. As a result, ULP drivers that choose to create a netdevice
with queue number that is less than the maximum channels mlx5 creates,
will get a memory corruption.
This fix changes the mlx5e netdev logic to respect ULP netdevices TX/RX
queue number and use it when creating resources instead of the maximum
channel number.

Currently we practically never report checksum unnecessary, because
for all IP packets we take the checksum complete path.
Enable non-default runs with reprorting checksum unnecessary, using
an ethtool private flag. This can be useful for performance evals
and other explorations.
