Jeff Kirsher says: ==================== 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
