Allow the user to configure where on the cable the TDR data should be
retrieved, in terms of first and last sample, and the step between
samples. Also add the ability to ask for TDR data for just one pair.
If this configuration is not provided, it defaults to 1-150m at 1m
intervals for all pairs.

The flash memory for the ice hardware contains a block of information
used for link management called the Netlist module.
As this essentially represents another section of firmware, add its
version information to the output of the driver's .info_get handler.
This includes both a version and the first few bytes of a hash of the
module contents.
fw.netlist -> the version information extracted from the netlist module
fw.netlist.build-> first 4 bytes of the hash of the contents, similar
to fw.mgmt.build

This UAPI is needed for BroadR-Reach 100BASE-T1 devices. Due to lack of
auto-negotiation support, we needed to be able to configure the
MASTER-SLAVE role of the port manually or from an application in user
space.
The same UAPI can be used for 1000BASE-T or MultiGBASE-T devices to
force MASTER or SLAVE role. See IEEE 802.3-2018:
22.2.4.3.7 MASTER-SLAVE control register (Register 9)
22.2.4.3.8 MASTER-SLAVE status register (Register 10)
40.5.2 MASTER-SLAVE configuration resolution
45.2.1.185.1 MASTER-SLAVE config value (1.2100.14)
45.2.7.10 MultiGBASE-T AN control 1 register (Register 7.32)
The MASTER-SLAVE role affects the clock configuration:
-------------------------------------------------------------------------------
When the PHY is configured as MASTER, the PMA Transmit function shall
source TX_TCLK from a local clock source. When configured as SLAVE, the
PMA Transmit function shall source TX_TCLK from the clock recovered from
data stream provided by MASTER.

-------------------------------------------------------------------------------
Since some clock or link related issues are only reproducible in a
specific MASTER-SLAVE-role, MAC and PHY configuration, it is beneficial
to provide generic (not 100BASE-T1 specific) interface to the user space
for configuration flexibility and trouble shooting.

Implement the upcoming rev of RFC4941 (IPv6 temporary addresses):
https://tools.ietf.org/html/draft-ietf-6man-rfc4941bis-09
* Reduces the default Valid Lifetime to 2 days
The number of extra addresses employed when Valid Lifetime was
7 days exacerbated the stress caused on network
elements/devices. Additionally, the motivation for temporary
addresses is indeed privacy and reduced exposure. With a
default Valid Lifetime of 7 days, an address that becomes
revealed by active communication is reachable and exposed for
one whole week. The only use case for a Valid Lifetime of 7
days could be some application that is expecting to have long
lived connections. But if you want to have a long lived
connections, you shouldn't be using a temporary address in the
first place. Additionally, in the era of mobile devices, general
applications should nevertheless be prepared and robust to
address changes (e.g. nodes swap wifi <-> 4G, etc.)
* Employs different IIDs for different prefixes
To avoid network activity correlation among addresses configured
for different prefixes
* Uses a simpler algorithm for IID generation
No need to store "history" anywhere

Currently users have to choose a free snapshot id before
calling DEVLINK_CMD_REGION_NEW. This is potentially racy
and inconvenient.
Make the DEVLINK_ATTR_REGION_SNAPSHOT_ID optional and try
to allocate id automatically. Send a message back to the
caller with the snapshot info.
Example use:
$ devlink region new netdevsim/netdevsim1/dummy
netdevsim/netdevsim1/dummy: snapshot 1
$ id=$(devlink -j region new netdevsim/netdevsim1/dummy | \
jq '.[][][][]')
$ devlink region dump netdevsim/netdevsim1/dummy snapshot $id
[...]
$ devlink region del netdevsim/netdevsim1/dummy snapshot $id
v4:
- inline the notification code
v3:
- send the notification only once snapshot creation completed.
v2:
- don't wrap the line containing extack;
- add a few sentences to the docs.
