Subject: [RFC Patch net-next 0/2] net: dsa: microchip: add support for Credit based shaper

LAN937x switch family, KSZ9477, KSZ9567, KSZ8567, KSZ9563 and KSZ8563 supports
the credit based shaper. But there were few difference between LAN937x and KSZ
switch like
- number of queue for LAN937x is 8 and for others it is 4.
- Size of credit increment register for LAN937x is 24 and for other is 16-bit.
This patch series add the credit based shaper with common implementation for
LAN937x and KSZ swithes.
