In the following scenario WoL isn't configured properly:
- Driver is loaded, interface isn't brought up within 10s, so driver
  runtime-suspends.
- WoL is set.
- Interface is brought up, stored WoL setting isn't applied.

It has always been like that, but the scenario seems to be quite
theoretical as I haven't seen any bug report yet. Therefore treat
the change as an improvement.

Use vzalloc/vzalloc_node instead of the vmalloc/vzalloc_node and memset.

Also, notice that vzalloc_node() function has no 2-factor argument form
to calculate the size for the allocation, so multiplication factors need
to be wrapped in array_size().

The CONFIG_PM_SLEEP #ifdef checks in this file are inconsistent,
leading to a warning about sometimes unused function:

drivers/net/ethernet/intel/e1000e/netdev.c:137:13: error: unused function 'e1000e_check_me' [-Werror,-Wunused-function]

Rather than adding more #ifdefs, just remove them completely
and mark the PM functions as __maybe_unused to let the compiler
work it out on it own.

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.

e1000_suspend() calls __e1000_shutdown() to perform intermediate tasks.
__e1000_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.

Currently the system will be woken up via WOL(Wake On LAN) even if the
device wakeup ability has been disabled via sysfs:
 cat /sys/devices/pci0000:00/0000:00:1f.6/power/wakeup
 disabled

The system should not be woken up if the user has explicitly
disabled the wake up ability for this device.

This patch clears the WOL ability of this network device if the
user has disabled the wake up ability in sysfs.

The port's headroom buffers are used to store packets while they
traverse the device's pipeline and also to store packets that are egress
mirrored.

On Spectrum-3, ports with eight lanes use two headroom buffers between
which the configured headroom size is split.

In order to prevent packet loss, multiply the calculated headroom size
by two for 8x ports.
