ixgbe: fix incorrect map used in eee linkmode

2025-09-02T18:08:59Z

incorrectly used ixgbe_lp_map in loops intended to populate the supported and advertised EEE linkmode bitmaps based on ixgbe_ls_map. This results in incorrect bit setting and potential out-of-bounds access, since ixgbe_lp_map and ixgbe_ls_map have different sizes and purposes. ixgbe_lp_map[i] -> ixgbe_ls_map[i] Use ixgbe_ls_map for supported and advertised linkmodes, and keep ixgbe_lp_map usage only for link partner (lp_advertised) mapping.

eth: intel: use vmalloc_array() to simplify code

2025-08-19T00:49:51Z

Remove array_size() calls and replace vmalloc() with vmalloc_array() to simplify the code and maintain consistency with existing kmalloc_array() usage. vmalloc_array() is also optimized better, resulting in less instructions being used.

ixgbe: add link_down_events statistic

2025-06-09T16:56:18Z

Introduce a link_down_events counter to the ixgbe driver, incremented each time the link transitions from up to down. This counter can help diagnose issues related to link stability, such as port flapping or unexpected link drops. The value is exposed via ethtool's get_link_ext_stats() interface.

Legacy implementation of .set_phys_id() ethtool callback is not applicable for E610 device. Add new implementation which uses 0x06E9 command by calling ixgbe_aci_set_port_id_led().

ixgbe: add support for ACPI WOL for E610

2025-04-29T22:13:43Z

Currently only APM (Advanced Power Management) is supported by the ixgbe driver. It works for magic packets only, as for different sources of wake-up E610 adapter utilizes different feature. Add E610 specific implementation of ixgbe_set_wol() callback. When any of broadcast/multicast/unicast wake-up is set, disable APM and configure ACPI (Advanced Configuration and Power Interface).

ixgbe: create E610 specific ethtool_ops structure

2025-04-29T22:13:43Z

E610's implementation of various ethtool ops is different than the ones corresponding to ixgbe legacy products. Therefore create separate E610 ethtool_ops struct which will be filled out in the forthcoming patches. Add adequate ops struct basing on MAC type. This step requires changing a bit the flow of probing by placing ixgbe_set_ethtool_ops after hw.mac.type is assigned. So move the whole netdev assignment block after hw.mac.type is known. This step doesn't have any additional impact on probing sequence.

ixgbe: add support for devlink reload

2025-04-15T14:36:33Z

The E610 adapters contain an embedded chip with firmware which can be updated using devlink flash. The firmware which runs on this chip is referred to as the Embedded Management Processor firmware (EMP firmware). Activating the new firmware image currently requires that the system be rebooted. This is not ideal as rebooting the system can cause unwanted downtime. The EMP firmware itself can be reloaded by issuing a special update to the device called an Embedded Management Processor reset (EMP reset). This reset causes the device to reset and reload the EMP firmware. Implement support for devlink reload with the "fw_activate" flag. This allows user space to request the firmware be activated immediately.
