Arrays with designated initializers have an implicit length of the highest
initialized value plus one. I used this to ensure that newly added entries
in enum bpf_reg_type get a NULL entry in compatible_reg_types.
This is difficult to understand since it requires knowledge of the
peculiarities of designated initializers. Use __BPF_ARG_TYPE_MAX to size
the array instead.

====================
mlx5-updates-2020-09-21
Multi packet TX descriptor support for SKBs.
This series introduces some refactoring of the regular TX data path in
mlx5 and adds the Enhanced TX MPWQE feature support. MPWQE stands for
multi-packet work queue element, and it can serve multiple packets,
reducing the PCI bandwidth spent on control traffic. It should improve
performance in scenarios where PCI is the bottleneck, and xmit_more is
signaled by the kernel. The refactoring done in this series also
improves the packet rate on its own.
MPWQE is already implemented in the XDP tx path, this series adds the
support of MPWQE for regular kernel SKB tx path.
MPWQE is supported from ConnectX-5 and onward, for legacy devices we need
to keep backward compatibility for regular (Single packet) WQE descriptor.
MPWQE is not compatible with certain offloads and features, such as TLS
offload, TSO, nonlinear SKBs. If such incompatible features are in use,
the driver gracefully falls back to non-MPWQE per SKB.
Prior to the final patch "net/mlx5e: Enhanced TX MPWQE for SKBs" that adds
the actual support, Maxim did some refactoring to the tx data path to
split it into stages and smaller helper functions that can be utilized and
reused for both legacy and new MPWQE feature.
Performance testing:
UDP performance is improved in a single stream pktgen test:
Packet rate: 16.86 Mpps (±0.15 Mpps) -> 20.94 Mpps (±0.33 Mpps)
Instructions per packet: 434 -> 329
Cycles per packet: 158 -> 123
Instructions per cycle: 2.75 -> 2.67
TCP and XDP_TX single stream tests show no performance difference.
MPWQE can reduce PCI bandwidth:
PCI Gen2, pktgen at fixed rate of 36864000 pps on 24 CPU cores:
Inbound PCI utilization with MPWQE off: 80.3%
Inbound PCI utilization with MPWQE on: 59.0%
PCI Gen3, pktgen at fixed rate of 56064000 pps on 24 CPU cores:
Inbound PCI utilization with MPWQE off: 65.4%
Inbound PCI utilization with MPWQE on: 49.3%
MPWQE can also reduce CPU load, increasing the packet rate in case of
CPU bottleneck:
PCI Gen2, pktgen at full rate on 24 CPU cores:
Packet rate with MPWQE off: 37.5 Mpps
Packet rate with MPWQE on: 49.0 Mpps
PCI Gen3, pktgen at full rate on 24 CPU cores:
Packet rate with MPWQE off: 57.0 Mpps
Packet rate with MPWQE on: 66.8 Mpps
Burst size in all pktgen tests is 32.
CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz (x86_64)

Two minor conflicts:
1) net/ipv4/route.c, adding a new local variable while
moving another local variable and removing it's
initial assignment.
2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
One pretty prints the port mode differently, whilst another
changes the driver to try and obtain the port mode from
the port node rather than the switch node.

The CAN-FD protocol allows the transmission and reception of data at a
higher bit rate than the nominal rate used in the arbitration phase when
the message's BRS bit is set.
The TDC mechanism is effective only during the data phase of FD frames
having BRS bit set. It has no effect either on non-FD frames, or on FD
frames transmitted at normal bit rate.

ISO CAN FD is introduced to increase the failture detection capability
than non-ISO CAN FD. The non-ISO CAN FD is still supported by FlexCAN so
that it can be used mainly during an intermediate phase, for evaluation
and development purposes.
Therefore, it is strongly recommended to configure FlexCAN to the ISO
CAN FD protocol by setting the ISOCANFDEN field in the CTRL2 register.
NOTE: If you only set "fd on", driver will use ISO FD mode by default.
You should set "fd-non-iso on" after setting "fd on" if you want to use
NON ISO FD mode.

On the i.MX7D in LPSR mode, the controller will be powered off and the
configuration state is lost after system resume. Upcoming i.MX8QM/QXP
will also completely power off the domain, the controller state is lost
and needs restore, too. So we need to set the pinctrl state again and
re-start chip to re-configuration after resume.
For the wakeup case, it should not set pinctrl to sleep state by
pinctrl_pm_select_sleep_state.
If the interface is down before suspend, we don't need to re-configure
it as it will be configured if the interface is brought up later.

commit cdce844865be ("can: flexcan: add vf610 support for FlexCAN")
From above commit by Stefan Agner, the patch just disables
non-correctable errors interrupt and freeze mode. It still can correct
the correctable errors since ECC enabled by default after reset (MECR[ECCDIS]=0,
enable memory error correct) if HW supports ECC.
commit 5e269324db5a ("can: flexcan: disable completely the ECC mechanism")
From above commit by Joakim Zhang, the patch disables ECC completely (assert
MECR[ECCDIS]) according to the explanation of FLEXCAN_QUIRK_DISABLE_MECR that
disable memory error detection. This cause correctable errors cannot be
corrected even HW supports ECC.
The error correction mechanism ensures that in this 13-bit word, errors
in one bit can be corrected (correctable errors) and errors in two bits can
be detected but not corrected (non-correctable errors). Errors in more than
two bits may not be detected.
If HW supports ECC, we can use this to correct the correctable errors detected
from FlexCAN memory. Then disable non-correctable errors interrupt and freeze
mode to avoid that put FlexCAN in freeze mode.
This patch adds correctable errors correction when HW supports ECC, and
modify explanation for FLEXCAN_QUIRK_DISABLE_MECR.

Fix this by refactoring debugfs code to debugfs.c. This also reduces the number
of ifdefs in debug.c and makes it easier to maintain the code.
No functional changes. Compile tested only.

This is a small update to fix an error I saw where a few functions do not
have a blank line in between them.
Affects smd.c and main.c - no logic is affected by this change.

This commit marks all smd.c functions that are only used inside of smd.c as
static. Previous commits added some VHT specific setup functions non-static
which is the right thing to do in terms of having granular git commits that
compile warning free. What we really want is for local not global scope on
those functions.
This patch makes the conversion from global to local scope.

This patch adds ieee802.11 VHT flags for the wcn3680b.
- RX_STBC1
- SU Beamformee
- MU Beamformee
- VHT80 SGI
- Single spatial stream
RX LDPC is declared as supported in the datasheet but not enabled at this
time.
After this patch is applied an AP should see the wcn3680 as an 802.11ac
capable device.

This commit adds VHT rates to the wcn36xx_update_allowed_rates() routine.
Thus allowing the driver to latch the declared rates and transmit them to
the firmware in the same way as other 80211.n rates are.

In order to send VHT parameters to wcn3680 we need to pass the extended V1
parameter structures to the firmware. These commands need to have the
version number set to 1.
This patch makes the conversion. The conversion consists of
1. Setting the version number for wcn3680 or leaving it at 0 otherwise
2. Setting the size of the packet header lower for wcn3620 and wcn3660
Once done all three chips can continue to use the same code to pass
parameters to their respective firmware. In the case of the wcn3680 the
passed structures will be slightly larger to accommodate communication of
VHT descriptors.

In order to pass 802.11ac VHT parameters from the SoC to wcn36xx we need to
use the V1 data structures associated with BSS and STA parameters.
The means of identifying a V1 data-structure is via the SMD version field.
This patch defines a INIT_HAL_MSG_V1() which operates the same way as
INIT_HAL_MSG() with the exception that it defines VERSION1 as opposed to
VERSION0.
