This patch adds support for Credit-Based Shaper (CBS) qdisc offload from Traffic Control system. This support enable us to leverage the Forwarding and Queuing for Time-Sensitive Streams (FQTSS) features from Intel i210 Ethernet Controller. FQTSS is the former 802.1Qav standard which was merged into 802.1Q in 2014. It enables traffic prioritization and bandwidth reservation via the Credit-Based Shaper which is implemented in hardware by i210 controller. The patch introduces the igb_setup_tc() function which implements the support for CBS qdisc hardware offload in the IGB driver. CBS offload is the only traffic control offload supported by the driver at the moment. FQTSS transmission mode from i210 controller is automatically enabled by the IGB driver when the CBS is enabled for the first hardware queue. Likewise, FQTSS mode is automatically disabled when CBS is disabled for the last hardware queue. Changing FQTSS mode requires NIC reset. FQTSS feature is supported by i210 controller only.
