====================
Intel Wired LAN Driver Updates 2023-12-01 (ice)

This series contains updates to ice driver only.

Konrad provides temperature reporting via hwmon.

Arkadiusz adds reporting of Clock Generation Unit (CGU) information via
devlink info.

Pawel adjusts error messaging for ntuple filters to account for additional
possibility for encountering an error.

Karol ensures that all timestamps occurring around reset are processed and
renames some E822 functions to convey additional usage for E823 devices.

Jake provides mechanism to ensure that all timestamps on E822 devices
are processed.

The following are changes since commit 15bc812:
  octeon_ep: set backpressure watermark for RX queues
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE
