mlxsw: reg: Extend QPCR register (2b84d7c3) · Commits · 戴 / test

The QoS Policer Configuration Register (QPCR) is used to configure hardware policers. Extend this register with following fields and defines which will be used by subsequent patches: 1. Violate counter: reads number of packets dropped by the policer 2. Clear counter: to ensure we start counting from 0 3. Rate and burst size limits Signed-off-by:
