Following the addition of new GTP RSS hash options to ethtool.h, this patch
implements the corresponding RSS settings for GTP packets in the Intel ice
driver. It enables users to configure RSS for GTP-U and GTP-C traffic over IPv4
and IPv6, utilizing the newly defined hash options.
The implementation covers the handling of gtpu(4|6), gtpc(4|6), gtpc(4|6)t,
gtpu(4|6)e, gtpu(4|6)u, and gtpu(4|6)d traffic, providing enhanced load
distribution for GTP traffic across multiple processing units.

Add support for SRIOV: send the requested number of VFs
to the device Control Plane, via the virtchnl message
and then enable the VFs using 'pci_enable_sriov'.
Add other ndo ops supported by the driver such as features_check,
set_rx_mode, validate_addr, set_mac_address, change_mtu, get_stats64,
set_features, and tx_timeout. Initialize the statistics task which
requests the queue related statistics to the CP. Add loopback
and promiscuous mode support and the respective virtchnl messages.
Finally, add documentation and build support for the driver.

There was a change previously to stop SR-IOV and LAG from existing on the
same interface. This was to prevent the violation of LACP (Link
Aggregation Control Protocol). The method to achieve this was to add a
no-op Rx handler onto the netdev when SR-IOV VFs were present, thus
blocking bonding, bridging, etc from claiming the interface by adding
its own Rx handler. Also, when an interface was added into a aggregate,
then the SR-IOV capability was set to false.
There are some users that have in house solutions using both SR-IOV and
bridging/bonding that this method interferes with (e.g. creating duplicate
VFs on the bonded interfaces and failing between them when the interface
fails over).
It makes more sense to provide the most functionality
possible, the restriction on co-existence of these features will be
removed. No additional functionality is currently being provided beyond
what existed before the co-existence restriction was put into place. It is
up to the end user to not implement a solution that would interfere with
existing network protocols.

Previously support for GNSS was implemented as a TTY driver, it allowed
to access GNSS receiver on /dev/ttyGNSS_<bus><func>.
Use generic GNSS subsystem API instead of implementing own TTY driver.
The receiver is accessible on /dev/gnss<id>. In case of multiple receivers
in the OS, correct device can be found by enumerating either:
- /sys/class/net/<eth port>/device/gnss/
- /sys/class/gnss/gnss<id>/device/
Using GNSS subsystem is superior to implementing own TTY driver, as the
GNSS subsystem was designed solely for this purpose. It also implements
TTY driver but in a common and defined way.
From user perspective, there is no difference in communicating with a
device, except new path to the device shall be used. The device will
provide same information to the userspace as the old one, and can be used
in the same way, i.e.:
old # gpsmon /dev/ttyGNSS_2100_0
new # gpsmon /dev/gnss0
There is no other impact on userspace tools.
User expecting onboard GNSS receiver support is required to enable
CONFIG_GNSS=y/m in kernel config.

Commit a296d665eae1 ("ixgbe: Add ethtool support to enable 2.5 and 5.0
Gbps support") introduced suppression of the advertisement of NBASE-T
speeds by default, according to Todd Fujinaka to accommodate customers
with network switches which could not cope with advertised NBASE-T
speeds, as posted in the E1000-devel mailing list:
https://sourceforge.net/p/e1000/mailman/message/37106269/
However, the suppression was not documented at all, nor was how to
enable NBASE-T support.
Properly document the NBASE-T suppression and how to enable NBASE-T
support.

Probably because the original file was pre-processed by some
tool, both i40e.rst and iavf.rst files are using this character:
- U+2013 ('–'): EN DASH
meaning an hyphen when calling a command line application, which
is obviously wrong. So, replace them by an hyphen, ensuring
that it will be properly displayed as literals when building
the documentation.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Organize driver documentation by device type. Most documents
have fairly verbose yet uninformative names, so let users
first select a well defined device type, and then search for
a particular driver.
While at it rename the section from Vendor drivers to
Hardware drivers. This seems more accurate, besides people
sometimes refer to out-of-tree drivers as vendor drivers.
