====================
Intel Wired LAN Driver Updates for 2023-10-25 (ice)

This series extends the ice driver with basic support for the E830 device
line. It does not include support for all device features, but enables basic
functionality to load and pass traffic.

Alice adds the 200G speed and PHY types supported by E830 hardware.

Dan extends the DDP package logic to support the E830 package segment.

Paul adds the basic registers and macros used by E830 hardware, and adds
support for handling variable length link status information from firmware.

Pawel removes some redundant zeroing of the PCI IDs list, and extends the
list to include the E830 device IDs.
