Several of the switch families in this driver have switches with AVB
support. The switches with AVB support have support for Credit based
shaping. This series adds support for the 6352, 6390 and 6393 families.
The difference between the families is:
- total number of queues
- which queues support credit based shaping
- shaping granularity

Eg. setting up 20mbps credit based shaper on a 1GBit link:
tc qdisc add dev p8 parent root handle 100: mqprio \
    num_tc 8 \
    map 0 0 6 7 0 5 0 0 0 0 0 0 0 0 0 0 \
    queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
    hw 0

tc qdisc replace dev p8 parent 100:8 cbs locredit -1470 hicredit 30 \
    sendslope -980000 idleslope 20000 offload 1
