Hello, This series introduces the CPSW Proxy Client driver to interface with Ethernet Switch Firmware (EthFw) running on a remote core on TI's K3 SoCs. Further details are in patch 01/28 which adds documentation for the driver and describes the intended use-case, design and execution of the driver. Please DO NOT MERGE this series. I will appreciate feedback on this series in the form of both documentation enhancements and code review. This series does not depend on other series and applies cleanly on the latest net-next commit: 4b377b4868ef kprobe/ftrace: fix build error due to bad function definition However, for purposes of functionality, device-tree changes are required in the form of a device-tree overlay in order to mark device-tree nodes as reserved for EthFw's use. I have tested this series on J721E EVM verifying: 1. Ping/Iperf 2. Interface Up-Down 3. Module Removal Linux Logs: https://gist.github.com/Siddharth-Vadapalli-at-TI/0972e74383cd1ec16e2f82c0d447f90b EthFw Logs corresponding to the Linux Logs shared above: https://gist.github.com/Siddharth-Vadapalli-at-TI/28743298daf113f90be9ceb26c46b16b Regards, Siddharth.
