This series contains updates to e1000e and igc drivers.
Ben Dooks adds a missing cpu_to_le64() in the e1000e transmit ring flush
function.
Jia-Ju Bai replaces a couple of udelay() with usleep_range() where we
could sleep while holding a spinlock in e1000e.
Chen Zhou make 2 functions static in igc,
Sasha finishes the legacy power management support in igc by adding
resume and schedule suspend requests. Also added register dump
functionality in the igc driver. Added device id support for the next
generation of i219 devices in e1000e. Fixed a typo in the igc driver
that referenced a device that is not support in the driver. Added the
missing PTP support when suspending now that igc has legacy power
management support. Added PCIe error detection, slot reset and resume
capability in igc. Added WoL support for igc as well. Lastly, added a
code comment to distinguish between interrupt and flag definitions.
Vitaly adds device id support for Tiger Lake platforms, which has
another next generation of i219 device in e1000e.
The following are changes since commit 7d51a01599d5285fc94fa4fcea10afabfa9ca5a4:
net: mvneta: align xdp stats naming scheme to mlx5 driver

The following warning suggests there is a missing cpu_to_le64() in
the e1000_flush_tx_ring() function (it is also the behaviour
elsewhere in the driver to do cpu_to_le64() on the buffer_addr
when setting it)

The driver may sleep while holding a spinlock.
The function call path (from bottom to top) in Linux 4.19 is:

drivers/net/ethernet/intel/e1000e/netdev.c, 5944:
spin_lock in e1000e_get_stats64
(FUNC_PTR) means a function pointer is called.
To fix these bugs, usleep_range() is replaced with udelay().
These bugs are found by a static analysis tool STCheck written by myself.

From: Sasha Neftin <sasha.neftin@intel.com>
commit 5f2958052c58 ("igc: Add basic skeleton for PTP") added basic
support for PTP, what's missing is support for suspending.
Legacy power management has been added. Now we can add
the suspend method to the igc_shutdown.
By cleaning the runtime storage for timestamp this avoids a possible
invalid memory access when the system comes back from suspend state.
