This updates the driver to align with the version included in the "Intel Ethernet Adapter Complete Driver Pack", version 25.6. There are no major functional changes; this mostly contains bug fixes and changes to prepare for new features. This version of the driver uses the previously committed ice_ddp package 1.3.19.0.
