Hello, This series extends the current ICSSG-based Ethernet driver to support 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 communicate commands to 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 first version of this patch series can be found in [2].
