- Adds FW logging support
  - Once enabled, this lets the firmware print event and error messages
    to the log, increasing the visibility into what the hardware is
    doing; this is useful for debugging
- General bug fixes
- Adds inital DCB support to the driver
  - Notably, this adds support for DCBX to the driver; now with the
    fw_lldp sysctl set to 1, the driver and adapter will adopt a DCBX
    configuration sent from a link partner
  - Adds statistcs sysctls for priority flow control frames
  - Adds new configuration sysctls for DCB-related features: (VLAN) user
    priority to TC mapping; ETS bandwidth allocation; priority flow
    control
- Remove unused SR-IOV files (until support gets added)

Includes various feature improvements and bug fixes.

Notable changes include:
- Firmware logging support
- Link management flow changes
- New sysctl to report aggregated error counts
- Health Status Event reporting from firmware (Use the new read-only
  tunables hw.ice.enable_health_events / dev.ice.#.enable_health_events
  to turn this off)

(cherry picked from commit 9cf1841c4aaf8fbab06132ab9f76094f34ad7c7b)

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.

(cherry picked from commit d08b8680e12ad692736c84238dcf45c70c228914)

Summary of changes:

- Assorted bug fixes
- Support for newer versions of the device firmware
- Suspend/resume support
- Support for Lenient Link Mode for E82X devices (e.g. can try to link with
  SFP/QSFP modules with bad EEPROMs)
- Adds port-level rx_discards sysctl, similar to ixl(4)'s

This version of the driver is intended to be used with DDP package 1.3.16.0,
which has already been updated in a previous commit.

The ice(4) driver is the driver for the Intel E8xx series Ethernet
controllers; currently with codenames Columbiaville and
Columbia Park.

These new controllers support 100G speeds, as well as introducing
more queues, better virtualization support, and more offload
capabilities. Future work will enable virtual functions (like
in ixl(4)) and the other functionality outlined above.

For full functionality, the kernel should be compiled with
"device ice_ddp" like in the amd64 NOTES file, and/or
ice_ddp_load="YES" should be added to /boot/loader.conf so that
the DDP package file included in this commit can be downloaded
to the adapter. Otherwise, the adapter will fall back to a single
queue mode with limited functionality.

A man page for this driver will be forthcoming.
