Subject: [PATCH net 2/2] net: stmmac: move fixed-link support fixup code
Date:   Mon, 13 Mar 2023 16:01:35 +0800

xpcs_an_inband value is updated in the speed_mode_2500 function
which turns on the xpcs_an_inband mode.

Moving the fixed-link fixup code to right before phylink setup to
ensure no more fixup will affect the fixed-link mode configurations.

Fixes: 72edaf39fc65 ("stmmac: intel: add phy-mode and fixed-link ACPI _DSD setting support")
