This series contains updates to e100, e1000, e1000e, igb, igbvf, ixgbe,
ixgbevf, iavf, and driver documentation.

Vaibhav Gupta converts legacy .suspend() and .resume() to generic PM
callbacks for e100, igbvf, ixgbe, ixgbevf, and iavf.

Suraj Upadhyay replaces 1 byte memsets with assignments for e1000,
e1000e, igb, and ixgbe.

Alexander Klimov replaces http links with https.

Miaohe Lin replaces uses of memset to clear MAC addresses with
eth_zero_addr().

The following are changes since commit 41d707b7332f1386642c47eb078110ca368a46f5:
  fib: fix fib_rules_ops indirect calls wrappers
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 1GbE

Alexander A. Klimov (1):
  Documentation: intel: Replace HTTP links with HTTPS ones

Miaohe Lin (2):
  ixgbe: use eth_zero_addr() to clear mac address
  igb: use eth_zero_addr() to clear mac address

Suraj Upadhyay (4):
  e1000: Remove unnecessary usages of memset
  e1000e: Remove unnecessary usages of memset
  igb: Remove unnecessary usages of memset
  ixgbe: Remove unnecessary usages of memset

Vaibhav Gupta (5):

With the support of generic PM callbacks, drivers no longer need to use
legacy .suspend() and .resume() in which they had to maintain PCI states
changes and device's power state themselves. The required operations are
done by PCI core.

PCI drivers are not expected to invoke PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_set_power_state(), etc. Their tasks are completed by PCI core itself.

Compile-tested only.

Remove legacy PM callbacks and use generic operations. With legacy code,
drivers were responsible for handling PCI PM operations like
pci_save_state(). In generic code, all these are handled by PCI core.

The generic suspend() and resume() are called at the same point the legacy
ones were called. Thus, it does not affect the normal functioning of the
driver.

__maybe_unused attribute is used with .resume() but not with .suspend(), as
.suspend() is called by .shutdown().

Compile-tested only.

From: Vaibhav Gupta <vaibhavgupta40@gmail.com>

With legacy PM hooks, it was the responsibility of a driver to manage PCI
states and also the device's power state. The generic approach is to let
PCI core handle the work.

ixgbe_suspend() calls __ixgbe_shutdown() to perform intermediate tasks.
__ixgbe_shutdown() modifies the value of "wake" (device should be wakeup
enabled or not), responsible for controlling the flow of legacy PM.

Since, PCI core has no idea about the value of "wake", new code for generic
PM may produce unexpected results. Thus, use "device_set_wakeup_enable()"
to wakeup-enable the device accordingly.

Compile-tested only.

From: Vaibhav Gupta <vaibhavgupta40@gmail.com>

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

The driver was invoking PCI helper functions like pci_save/restore_state(),
and pci_enable/disable_device(), which is not recommended.

Compile-tested only.

From: Vaibhav Gupta <vaibhavgupta40@gmail.com>

With legacy PM hooks, it was the responsibility of a driver to manage PCI
states and also the device's power state. The generic approach is to let
PCI core handle the work.

e100_suspend() calls __e100_shutdown() to perform intermediate tasks.
__e100_shutdown() calls pci_save_state() which is not recommended.

e100_suspend() also calls __e100_power_off() which is calling PCI helper
functions, pci_prepare_to_sleep(), pci_set_power_state(), along with
pci_wake_from_d3(...,false). Hence, the functin call is removed and wol is
disabled as earlier using device_wakeup_disable().

Compile-tested only.

From: "Alexander A. Klimov" <grandmaster@al2klimov.de>

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.
