This series adds support for forcing 10/100 Mb/s link speed via ethtool
when autonegotiation is disabled on the igc driver.

Changes in v2:
- Simon Horman's review comment: when forcing half-duplex, set
  hw->fc.requested_mode = igc_fc_none, since half-duplex cannot support
  flow control per IEEE 802.3.
- Split the original single patch into three patches for clarity:
  patches 1 and 2 are preparatory cleanups; patch 3 carries the
  functional change.

v1 at:
https://patchwork.ozlabs.org/project/intel-wired-lan/patch/20260409072747.217836-1-khai.wen.tan@linux.intel.com/

Faizal Rahim (3):
  igc: remove unused autoneg_failed field
  igc: move autoneg-enabled settings into igc_handle_autoneg_enabled()
  igc: add support for forcing link speed without autonegotiation
