====================
1GbE Intel Wired LAN Driver Updates 2019-12-31

This series contains updates to e1000e, igb and igc only.

Robert Beckett provide an igb change to assist in keeping packets from
being dropped due to receive descriptor ring being full when receive
flow control is enabled.  Create a separate function to setup SRRCTL to
ease in reuse and ensure that setting of the drop enable bit only if
receive flow control is not enabled.

Sasha adds support for scatter gather support in igc.  Improve the
direct memory address mapping flow by optimizing/simplifying and more
clear.  Update igc to use pci_release_mem_regions() instead of
pci_release_selected_regions().  Clean up function header comments to
align with the actual code.  Adds support for 64 bit DMA access, to help
handle socket buffer fragments in high memory.  Adds legacy power
management support in igc by implementing suspend, resume,
runtime_suspend/resume, and runtime_idle callbacks.  Clean up references
to Serdes interface in igc since that interface is not supported for
i225 devices.

Alex replaces the pr_info calls with netdev_info in all cases related to
netdev link state, as suggested by Joe Perches.
