From 98cd1552ea27e512c7e99e2aa76042a26e4fb25c Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 30 Mar 2017 18:43:21 -0700 Subject: net: dsa: Mock-up driver This patch adds support for a DSA mock-up driver which essentially does the following: - registers/unregisters 4 fixed PHYs to the slave network devices - uses eth0 (configurable) as the master netdev - registers the switch as a fixed MDIO device against the fixed MDIO bus at address 31 - includes dynamic debug prints for dsa_switch_ops functions that can be enabled to get call traces This is a good way to test modular builds as well as exercise the DSA APIs without requiring access to real hardware. This does not test the data-path, although this could be added later on. Signed-off-by: Florian Fainelli Signed-off-by: David S.
