The commit in the Fixes: tag below broke traffic through switch ports
where the SERDES protocol requires in-band autoneg and this requirement
isn't described in the device tree: SGMII, QSGMII, USXGMII (with
2500Base-X, in-band autoneg isn't supported).
The LS1028A-QDS boards are not yet ready for syncing their device trees
with Linux, since Ethernet is missing there (but has been submitted):
https://lore.kernel.org/lkml/20211112223457.10599-11-leoyang.li@nxp.com/
When agreement is reached for the Ethernet support in Linux, there will
be a sync for these boards as well. For now, just enable in-band autoneg
to fix the breakage.
Fixes: e3789a7262 ("net: dsa: felix: configure the in-band autoneg property based on OF node info")
