Hi all, This patch series enables Broadcom's Advanced Congestion Buffering mechanism which requires cooperation between the CPU/Management Ethernet MAC controller and the switch.
I took the notifier approach because ultimately the information we need to carry to the master network device is DSA specific and I saw little room for generalizing beyond what DSA requires. Chances are that this is highly specific to the Broadcom HW as I don't know of any HW out there that supports something nearly similar for similar or identical needs.
