Introduction
In 2022, many products were updated with a RTL8211 Ethernet PHY. Prior versions of these products used the Atheros (Qualcomm) AR8035 PHY, however this product became unavailable in 2022 due to supply chain limitations, and we were forced to updated many products in order to keep our customers in production.
Hardware Impacts
There is no hardware change made to the module or product that will incur or require a hardware change to the customer baseboard or system.
Software Impacts
There are software modifications required to add support for the RTL8211 PHY to both the bootloader and to the kernel. It is important to note that these changes DO NOT remove support for the older AR803x PHY support. Once these changes are included in your software, software will work on platforms with both AR803x PHY and the new RTL8211 PHY.
The following table lists commits made to support the RTL8211 PHY by product and software revision.
Changes are backported as far as kernel 4.14.98 for many platforms. If support for the platform was added later revisions, we have backported to the earliest revision where we had a stable release.
If a platform is not yet listed, please continue to check this article as it will be updated as patches are finalized and tested.
