Hello!
The current R-Car S4 rswitch driver only supports port based fowarding.
This patch set adds HW offloading for L2 switching/bridgeing. The driver
hooks into switchdev.
1. Rename the base driver file to keep the driver name (rswitch.ko)
2. Add the L2 driver extension in a separate file. The HW offloading
is automatically configured when a port is added to the bridge device.
Ussage example:
ip link add name br type bridge
ip link set dev tsn0 master br
ip link set dev tsn1 master br
ip link set dev br up
ip link set dev tsn0 up
ip link set dev tsn1 up
Layer 2 traffic is now fowarded by HW from port TSN0 to port TSN1.
3. Provides the functionality to set the MAC table ageing time in the
Rswitch.
Usage example:
brctl setageing br 300
Thanks,
Michael
