Subject: [RFC PATCH net-next 00/28] Add CPSW Proxy Client driver
Date: Sat, 18 May 2024 18:12:06 +0530

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
