>As explained in the previous patch "arm: dts: ls1028a-rdb: sync Ethernet
>device tree nodes with Linux", the commit below broke traffic through switch
>ports where the SERDES protocol requires in-band autoneg: SGMII, QSGMII,
>USXGMII (with 2500Base-X, in-band autoneg isn't supported).

Please write description independent of other patch or mention commit details
for better readability at later point.

>The LS1028A-QDS boards are not yet ready for syncing their device trees with
>Linux, since Ethernet is missing there (but has been submitted):

>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.
