We are currently accepting bug fixes only. Please repost when net-next reopens after March 25th. RFC patches sent for review only are welcome at any time.

Hello, This series extends the current ICSSG-based Ethernet driver to support AM65x Silicon Revision 1.0 devices. Notable differences between the Silicon Revisions are that there is no TX core in SR1.0 with this being handled by the firmware, requiring extra DMA channels to manage communication with the firmware (with the firmware being different as well) and in the packet classifier. The motivation behind it is that a significant number of Siemens devices containing SR1.0 silicon have been deployed in the field and need to be supported and updated to newer kernel versions without losing functionality. This series is based on TI's 5.10 SDK [1]. The fourth version of this patch series can be found in [2]. Detailed descriptions of the changes in this series can be found in each commit's message. Both of the problems mentioned in v4 have been addressed by disabling those functionalities, meaning that this driver currently only supports one TX queue and does not support a 100Mbit/s half-duplex connection. The removal of these features has been commented in the appropriate locations in the code.
