This series adds support for forcing 10/100 Mb/s link speed via ethtool
when autonegotiation is disabled on the igc driver.
Changes in v3:
- Modify condition from "if (duplex == DUPLEX_HALF)" to
"if (duplex != DUPLEX_FULL)". (Simon Horman)
Changes in v2:
- When forcing half-duplex, set hw->fc.requested_mode = igc_fc_none,
since half-duplex cannot support flow control per IEEE 802.3.
(Simon Horman)
- Split the original single patch into three patches for clarity:
patches 1 and 2 are preparatory cleanups; patch 3 carries the
functional change.

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
