Subject: [PATCH net v3 3/3] net: stmmac: remove redundant fixup to support fixed-link mode
Date:   Fri, 24 Mar 2023 16:16:56 +0800

Currently, intel_speed_mode_2500() will fix-up xpcs_an_inband
to 1 if the underlying controller has a max speed of 1000Mbps.
The value has been initialized and modified if it is
a fixed-linked setup earlier.

This patch removes the fix-up to allow for fixed-linked setup
support. In stmmac_phy_setup(), ovr_an_inband is set based on
the value of xpcs_an_inband. Which in turn will return an
error in phylink_parse_mode() where MLO_AN_FIXED and
ovr_an_inband are both set.

Fixes: c82386310d95 ("stmmac: intel: prepare to support 1000BASE-X phy interface setting")
