Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue
Tony Nguyen says:
====================
Intel Wired LAN Driver Updates 2025-04-29 (igb, igc, ixgbe, idpf)
For igb:
Kurt Kanzenbach adds linking of IRQs and queues to NAPI instances and
adds persistent NAPI config. Lastly, he removes undesired IRQs that
occur while busy polling.
For igc:
Kurt Kanzenbach switches the Tx mode for MQPRIO offload to harmonize the
current implementation with TAPRIO.
For ixgbe:
Jedrzej adds separate ethtool ops for E610 devices to account for device
differences.
Slawomir adds devlink region support for E610 devices.
For idpf:
Mateusz assigns and utilizes the ptype field out of libeth_rqe_info.
Michal removes unreachable code.
* '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
idpf: remove unreachable code from setting mailbox
idpf: assign extracted ptype to struct libeth_rqe_info field
ixgbe: devlink: add devlink region support for E610
ixgbe: add E610 .set_phys_id() callback implementation
ixgbe: apply different rules for setting FC on E610
ixgbe: add support for ACPI WOL for E610
ixgbe: create E610 specific ethtool_ops structure
igc: Change Tx mode for MQPRIO offloading
igc: Limit netdev_tc calls to MQPRIO
igb: Get rid of spurious interrupts
igb: Add support for persistent NAPI config
igb: Link queues to NAPI instances
igb: Link IRQs to NAPI instances
