In order to correctly drive mv88e6xxx hardware when the PCS code is split, we need to force the link down while changing the configuration of a port. This is provided for via the mac_prepare() and mac_finish() methods, but DSA does not forward these on to DSA drivers. Patch 1 adds support to the DSA core to forward these two methods to DSA drivers, and patch 2 moves the code from mv88e6xxx_mac_config() into the respective methods. drivers/net/dsa/mv88e6xxx/chip.c | 65 +++++++++++++++++++++++++++------------- include/net/dsa.h | 6 ++++ net/dsa/port.c | 32 ++++++++++++++++++++ 3 files changed, 83 insertions(+), 20 deletions(-) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
