While not explicitly documented as supported in UM10944, compliance with
the STP states can be obtained by manipulating 3 settings at the
(per-port) MAC config level: dynamic learning, inhibiting reception of
regular traffic, and inhibiting transmission of regular traffic.
In all these modes, transmission and reception of special BPDU frames
from the stack is still enabled (not inhibited by the MAC-level
settings).
On ingress, BPDUs are classified by the MAC filter as link-local
(01-80-C2-00-00-00) and forwarded to the CPU port. This mechanism works
under all conditions (even without the custom 802.1Q tagging) because
the switch hardware inserts the source port and switch ID into bytes 4
and 5 of the MAC-filtered frames. Then the DSA .rcv handler needs to put
back zeroes into the MAC address after decoding the source port
information.
On egress, BPDUs are transmitted using management routes from the xmit
worker thread. Again this does not require switch tagging, as the switch
port is programmed through SPI to hold a temporary (single-fire) route
for a frame with the programmed destination MAC (01-80-C2-00-00-00).
STP is activated using the following commands and was tested by
connecting two front-panel ports together and noticing that switching
loops were prevented (one port remains in the blocking state):
$ ip link add name br0 type bridge stp_state 1 && ip link set br0 up
$ for eth in $(ls /sys/devices/platform/soc/2100000.spi/spi_master/spi0/spi0.1/net/);
do ip link set ${eth} master br0 && ip link set ${eth} up; done

In order to support this, we are creating a make-shift switch tag out of
a VLAN trunk configured on the CPU port. Termination of normal traffic
on switch ports only works when not under a vlan_filtering bridge.
Termination of management (PTP, BPDU) traffic works under all
circumstances because it uses a different tagging mechanism
(incl_srcpt). We are making use of the generic CONFIG_NET_DSA_TAG_8021Q
code and leveraging it from our own CONFIG_NET_DSA_TAG_SJA1105.
There are two types of traffic: regular and link-local.
The link-local traffic received on the CPU port is trapped from the
switch's regular forwarding decisions because it matched one of the two
DMAC filters for management traffic.
On transmission, the switch requires special massaging for these
link-local frames. Due to a weird implementation of the switching IP, by
default it drops link-local frames that originate on the CPU port.
It needs to be told where to forward them to, through an SPI command
("management route") that is valid for only a single frame.
So when we're sending link-local traffic, we are using the
dsa_defer_xmit mechanism.

The Marvell SOHO switches have several ways to access the internal
registers. One of them being the System Management Interface (SMI),
using the MDC and MDIO pins, with direct and indirect variants.
In preparation for adding support for other register accesses, move
the SMI code into its own files. At the same time, refine the code
to make it clear that the indirect variant is implemented using the
direct variant accessing only two registers for command and data.

Many embedded devices have information such as MAC addresses stored
inside NVMEMs like EEPROMs and so on. Currently there are only two
drivers in the tree which benefit from NVMEM bindings.
Adding support for NVMEM into every other driver would mean adding a lot
of repetitive code. This patch allows us to configure MAC addresses in
various devices like ethernet and wireless adapters directly from
of_get_mac_address, which is already used by almost every driver in the
tree.
Predecessor of this patch which used directly MTD layer has originated
in OpenWrt some time ago and supports already about 497 use cases in 357
device tree files.

100GbE Intel Wired LAN Driver Updates 2019-05-04
This series contains updates to the ice driver only.
Jesse updated the driver to make more functions consistent in their use
of a local variable for vsi->back. Updates the driver to use bit fields
when possible to avoid wasting lots of storage space to store single bit
values. Optimized the driver to be more memory efficient by moving
structure members around that are not in are hot path.
Michal updates the driver to disable the VF if malicious device driver
(MDD) event is detected by the hardware. Adds checks to validate the
messages coming from the VF driver. Tightens up the sniffing of the
driver so that transmit traffic so that VF's cannot see what is on other
VSIs.
Tony fixed the driver so that receive stripping state won't change every
time transmit insertion is changed. Cleanup the __always_unused
attribute, now that the variable is being used. Fixed the function
which evaluates setting of features to ensure that can evaluate and set
multiple features in a single function call.
Akeem fixes the driver so that we do not attempt to remove a VLAN filter
that does not exist. Adds support for adding a ethertype based filter
rule on VSI and describe it in a very long run-on sentence. :-)
Bruce cleans up static analysis warnings by removing a local variable
initialization that is not needed.
Brett makes the allocate/deallocate more consistent in all the driver
flows for VSI q_vectors. In addition, makes setting/getting coalesce
settings more consistent throughout the driver.

vectors to ensure one does not exceed the other.
Martyna adds additional input validation on VF messages handled by the

HPWDT_NMI_DECODING depends on HP_WATCHDOG and should be next to it.
This helps menuconfig identify HPWDT_NMI_DECODING as depending on
HP_WATCHDOG.
BCM_KONA_WDT_DEBUG depends on BCM_KONA_WDT which depends on COMPILE_TEST.
Enabling BCM_KONA_WDT_DEBUG without BCM_KONA_WDT does not make sense,
so drop the COMPILE_TEST dependency from it. This also improves
menuconfig, which now properly associates BCM_KONA_WDT_DEBUG with
BCM_KONA_WDT.

Watchdog pretimeout governors were enabled from the default governor
selection using "select". As a result, the default governor was always
built into the kernel, even if no watchdog driver was loaded. By using
"depends on" instead of "select", we are in better control, and the
governors can all be built as modules. At the same time, set the default
configuration option for pretimeout governors to match WATCHDOG_CORE
(meaning all pretimeout governors are by default enabled if pretimeout
support is enabled).
The practical impact of this change is minimal. Previously, selecting
a default governor automatically enabled that governor. Now, a default
governor can only be selected if that governor has been enabled.
Consequently, the order of governor selection is now reversed: The
governor selection is now first, followed by default governor selection.

The Kconfig currently controlling compilation of this code is:

Lets remove the modular code that is essentially orphaned, so that

We also delete the MODULE_LICENSE tag etc. since all that information

We leave the moduleparam.h include since the file does declare some

way to remain compatible with existing boot arg use cases.
