Implement support for Credit-based shaper(CBS) Qdisc hardware offload mode in the driver. There are two sets of IEEE802.1Qav (CBS) HW logic in i225 controller and this patch supports enabling them in the top two priority TX queues. Driver implemented as recommended by Foxville External Architecture Specification v0.993. Idleslope and Hi-credit are the CBS tunable parameters for i225 NIC, programmed in TQAVCC and TQAVHC registers respectively. In-order for IEEE802.1Qav (CBS) algorithm to work as intended and provide BW reservation CBS should be enabled in highest priority queue first. If we enable CBS on any of low priority queues, the traffic in high priority queue does not allow low priority queue to be selected for transmission and bandwidth reservation is not guaranteed.
