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.

net: phy: relax PHY and MDIO reset handling

Previously these patches were submitted as part of a larger series[1]
but since the approach in it will have to be reworked I'm resending
the ones that were non-controversial and have been reviewed for upstream.

Florian suggested a better solution for managing multiple resets. While
I will definitely try to implement something at the driver model's bus
level (together with regulator support), the 'resets' and 'reset-gpios'
DT property is a stable ABI defined in mdio.yaml so improving its support
is in order as we'll have to stick with it anyway. Current implementation
contains an unnecessary limitation where drivers without probe() can't
define resets.

Changes from the previous version:
- order forward declarations in patch 4 alphabetically
- collect review tags

Similarily to PHY drivers - there's no reason to require probe() to be
implemented in order to call mdio_device_reset(). MDIO devices can have
resets defined without needing to do anything in probe().

Currently we only call phy_device_reset() if the PHY driver implements
the probe() callback. This is not mandatory and many drivers (e.g.
realtek) don't need probe() for most devices but still can have reset
GPIOs defined. There's no reason to depend on the presence of probe()
here so pull the reset code out of the if clause.

Some PHYs connected to this ethernet hardware support the WoL feature.
But when WoL is enabled and the machine is powered off, the PHY remains
waiting for a magic packet at max speed (i.e. 1Gbps), which is a waste of
energy.

Slow down the PHY speed before stopping the ethernet if WoL is enabled,
and save some energy while the machine is powered off or sleeping.

40GbE Intel Wired LAN Driver Updates 2020-06-25

This series contains updates to i40e driver and removes the individual
driver versions from all of the Intel wired LAN drivers.

Shiraz moves the client header so that it can easily be shared between
the i40e LAN driver and i40iw RDMA driver.

Jesse cleans up the unused defines, since they are just dead weight.

Alek reduces the unreasonably long wait time for a PF reset after reboot
by using jiffies to limit the maximum wait time for the PF reset to
succeed.  Added additional logging to let the user know when the driver
transitions into recovery mode.  Adds new device support for our 5 Gbps
NICs.

Todd adds a check to see if MFS is set after warm reboot and notifies
the user when MFS is set to anything lower than the default value.

Arkadiusz fixes a possible race condition, where were holding a
spin-lock while in atomic context.

As with other networking drivers, remove the unnecessary driver version
from the Intel drivers. The ethtool driver information and module version
will then report the kernel version instead.

For ixgbe, i40e and ice drivers, the driver passes the driver version to
the firmware to confirm that we are up and running.  So we now pass the
value of UTS_RELEASE to the firmware.  This adminq call is required per
the HAS document.  The Device then sends an indication to the BMC that the
PF driver is present. This is done using Host NC Driver Status Indication
in NC-SI Get Link command or via the Host Network Controller Driver Status
Change AEN.

What the BMC may do with this information is implementation-dependent, but
this is a standard NC-SI 1.1 command we honor per the HAS.

cake_handle_diffserv() tries to linearize mac and network header parts of

skb reallocation, which reduces throughput and increases CPU load. Some
measurements of IPv4 forward + NAPT on MIPS router with 580 MHz single-core
CPU was conducted. It appears that on kernel 4.9 skb_try_make_writable()
reallocates skb, if skb was allocated in ethernet driver via so-called
'build skb' method from page cache (it was discovered by strange increase
of kmalloc-2048 slab at first).

Obtain DSCP value via read-only skb_header_pointer() call, and leave
linearization only for DSCP bleaching or ECN CE setting. And, as an
additional optimisation, skip diffserv parsing entirely if it is not needed
by the current configuration.
