Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 

Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2019-09-12

This series contains updates to ice driver to implement and support
loading a Dynamic Device Personalization (DDP) package from lib/firmware
onto the device.

Paul updates the way the driver version is stored in the driver so that
we can pass the driver version to the firmware.  Passing of the driver
version to the firmware is needed for the DDP package to ensure we have
the appropriate support in the driver for the features in the package.

Lukasz fixes how the firmware version is stored to align with how the
firmware stores its own version.  Also extended the log message to
display additional useful information such as NVM version, API patch
information and firmware build hash.

Tony adds the needed driver support to check, load and store the DDP
package.  Also add support for the ability to load DDP packages intended
for specific hardware devices, as well as what to do when loading of the
DDP package fails to load.
