Jacob Keller says:

====================
Intel Wired LAN Updates 2024-04-30 (ixgbe, i40e, ice)

This series includes updates to support Energy-Efficient Ethernet (EEE) on
E610 devices in the ixgbe driver, support for an unmanaged DPLL output on
E830, as well as some other minor cleanups and improvements across ixgbe,
i40e, and ice.

Jedrzej begins with the first six patches preparing the ixgbe driver to
support EEE, adding a EEE capability flag, updating the supported EEE
speeds, updating the ACI command structures with the fields related to
EEE, moving the EEE config validation out for re-use, and finally
implementing the EEE support for E610 hardware.

Aleksandr fixes the ixgbe_update_flash_X550() logic to prevent unaligned
access in ixgbe_host_interface_command(). Note: this has no functional
change on x86, and is being sent through net-next as it is considered a
minor cleanup.

Jacob (hi!) modifies the i40e driver to only timestamp PTP event packets,
instead of timestamping every V2 event frame. This avoids wasting the
limited number of timestamp slots for frames which the PTP protocol does
not care about.

Jacob also extends the devlink flash notification message reporting that
users can activate the new firmware via devlink reload to explicitly
indicate the required "fw_activate" action.

Byungchul Park  fixes the ice_lbtest_receive_frames() function to use
netmem_desc instead of the page structure.

Przemyslaw Korba fixes a truncation warning in ice_dpll_init_fwnode_pins()
by increasing the allowed length of the pin_name string on the stack to 16.

Ivan Vecera adds some bounds checking to ice_dpll_rclk_state_on_pin_get/set()
and moves the CGU register macros to be under the header guard ifdef in
ice_dpll.h
