The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Remainder for "DT bindings for Felix DSA switch on LS1028A"
This series is the remainder of patchset [0] which has been merged
through Shawn Guo's devicetree tree.
It contains changes to the PHY mode validation in the Felix driver
("gmii" to "internal") and the documentation for the DT bindings.

This patch adds the required documentation for the embedded L2 switch
inside the NXP LS1028A chip.
I've submitted it in the legacy format instead of yaml schema, because
DSA itself has not yet been converted to yaml, and this driver defines
no custom bindings.

phy-mode = "gmii" is confusing because it may mean that the port
supports the 8-bit-wide parallel data interface pinout, which it
doesn't.
It may also be confusing because one of the "gmii" internal ports is
actually overclocked to run at 2.5Gbps (even though, yes, as far as the
switch MAC is concerned, it still thinks it's gigabit).
So use the phy-mode = "internal" property to describe the internal ports
inside the NXP LS1028A chip (the ones facing the ENETC). The change
should be fine, because the device tree bindings document is yet to be
introduced, and there are no stable DT blobs in use.

====================
Bare UDP L3 Encapsulation Module
There are various L3 encapsulation standards using UDP being discussed to
leverage the UDP based load balancing capability of different networks.
MPLSoUDP (__ https://tools.ietf.org/html/rfc7510) is one among them.
The Bareudp tunnel module provides a generic L3 encapsulation tunnelling
support for tunnelling different L3 protocols like MPLS, IP, NSH etc. inside
a UDP tunnel.
Special Handling
----------------
The bareudp device supports special handling for MPLS & IP as they can have
multiple ethertypes.
MPLS procotcol can have ethertypes ETH_P_MPLS_UC (unicast) & ETH_P_MPLS_MC (multicast).
IP protocol can have ethertypes ETH_P_IP (v4) & ETH_P_IPV6 (v6).
This special handling can be enabled only for ethertypes ETH_P_IP & ETH_P_MPLS_UC
with a flag called multiproto mode.
Usage
------
1) Device creation & deletion
a) ip link add dev bareudp0 type bareudp dstport 6635 ethertype 0x8847.
This creates a bareudp tunnel device which tunnels L3 traffic with ethertype
0x8847 (MPLS traffic). The destination port of the UDP header will be set to
6635.The device will listen on UDP port 6635 to receive traffic.
b) ip link delete bareudp0
2) Device creation with multiple proto mode enabled
There are two ways to create a bareudp device for MPLS & IP with multiproto mode
enabled.
a) ip link add dev bareudp0 type bareudp dstport 6635 ethertype 0x8847 multiproto
b) ip link add dev bareudp0 type bareudp dstport 6635 ethertype mpls
3) Device Usage
The bareudp device could be used along with OVS or flower filter in TC.
The OVS or TC flower layer must set the tunnel information in SKB dst field before
sending packet buffer to the bareudp device for transmission. On reception the
bareudp device extracts and stores the tunnel information in SKB dst field before
passing the packet buffer to the network stack.
Why not FOU ?
------------
FOU by design does l4 encapsulation.It maps udp port to ipproto (IP protocol number for l4 protocol).
Bareudp acheives a generic l3 encapsulation.It maps udp port to l3 ethertype.

Special handling is needed in bareudp module for IP & MPLS as they
support more than one ethertypes.
MPLS has 2 ethertypes. 0x8847 for MPLS unicast and 0x8848 for MPLS multicast.
While decapsulating MPLS packet from UDP packet the tunnel destination IP
address is checked to determine the ethertype. The ethertype of the packet
will be set to 0x8848 if the tunnel destination IP address is a multicast
IP address. The ethertype of the packet will be set to 0x8847 if the
tunnel destination IP address is a unicast IP address.
IP has 2 ethertypes.0x0800 for IPV4 and 0x86dd for IPv6. The version
field of the IP header tunnelled will be checked to determine the ethertype.
This special handling to tunnel additional ethertypes will be disabled
by default and can be enabled using a flag called multiproto. This flag can
be used only with ethertypes 0x8847 and 0x0800.

The IDT 82P33 Synchronization Management Unit (SMU) family provides
tools to manage timing references, clock sources and
timing paths for IEEE 1588 / Precision Time Protocol (PTP) and
Synchronous Ethernet (SyncE) based clocks. The device supports up
to three independent timing paths that control: PTP clock synthesis;
SyncE clock generation; and general purpose frequency translation.
The device supports physical layer timing with Digital PLLs (DPLLs)
and it supports packet based timing with Digitally Controlled
Oscillators (DCOs). This patch adds support for ptp clock based on
the device.
Changes since v1:
- As suggested by Richard Cochran:
1. Replace _mask_bit_count with the existing hweight8
2. Prefix all functions with idt82p33
3. Fix white space issues in Kconfig and Makefile
4. Remove forward declaration
5. Use adjfine instead of adjfreq for better resolution
- As suggested by David Miller:
1. Replace CHAN_INIT macro with a static function
idt82p33_channel_init
2. Employ reverse christmas tree ordering for local
variables
3. Fix indentation problem by appropriate number of
TAB then SPACE character

mlxsw: Introduce ACL traps
This patchset allows to track packets that are dropped in HW by ACL.
Unlike the existing mlxsw traps, ACL traps are "source traps".
That means the action is not controlled by HPKT register but directly
in ACL TRAP action. When devlink user changes action from drop to trap
and vice versa, it would be needed to go over all instances of ACL TRAP
action and do change. That does not scale. Instead, resolve this
by introducing "dummy" group with "thin" policer. The purpose of
this policer is to drop as many packets as possible. The ones
that pass through are going to be dropped in devlink code - patch #6
takes care of that.
First four patches are preparation for introduction of ACL traps in mlxsw
so it possible to easily change from drop to trap for source traps
as well - by changing group to "dummy" and back.

For "source traps" it is not possible to change HPKT action to discard.
But there is still need to disallow packets arriving to CPU as much as
possible. Handle this by introduction of a "dummy group". It has a
"thin" policer, which passes as less packets to CPU as possible. The
rest is going to be discarded there. The "dummy group" is to be used
later on by ACL trap (which is a "source trap").

Clean driver, module and FW versions
Change log:
v1:
* Split all FW cleanups patches to separate patches
* Fixed commit message
* Deleted odd DRV_RELDATE
* Added everyone from MAINTAINERS file
v0: https://lore.kernel.org/netdev/20200220145855.255704-1-leon@kernel.org
This is first patchset to netdev (already sent RDMA [1] and arch/um [2])
in attempt to unify the version management for in-tree kernel code.
The patches follow already accepted ethtool change [3] to set as
a default linux kernel version.
It allows us to remove driver version and present to the users unified
picture of driver version, which is similar to default MODULE_VERSION().
As part of this series, I deleted various creative attempts to mark
absence of FW. There is no need to set "N/A" in ethtool ->fw_version
field and it is enough to do not set it.
1.
The code is compile tested and passes 0-day kbuild.
2.
The proposed changes are based on commit:
2bb07f4e1d86 ("tc-testing: updated tdc tests for basic filter")
3.
WIP branch is [4].
