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")

|
* This setup is using SCH-24801 cards with VSC8234 quad SGMII PHY.
|
|
* LS1028A QDS boards with lane B rework require two cards for the 4 switch
|
|
* ports, QDS boards without the lane B rework only require one card.
|
|
*
|
|
* Switch ports are routed as follows:
|
|
* Port 0 goes to 1st port of VSC8234 quad card in slot 1,
|
|
* Port 1:
|
|
* - if the QDS has had lane B rework, it is 1st port in slot 2,
|
|
* - otherwise it is 2nd port in slot 1.
|
|
* Port 2:
|
|
* - if DIP SW5[1] = 0 it is 3rd port in slot 1,
|
|
* - otherwise it is 1st port in slot 3.
|
|
* Port 3:
|
|
* - if DIP SW5[2-3] = 00b it is 4th port in slot 1,
|
|
* - if DIP SW5[2-3] = 01b it is 2nd port in slot 3,
|
|
* - if DIP SW5[2-3] = 11b it is 1st port in slot 4.
|
|
*
|
|
* The following DTS assumes QDS lane B rework and DIP SW5[1-3] = 000b. Two
|
|
* SCH-24801 cards are required in slots 1 and 2.
