CPSW host port

Introduction

The CPSW statistics module implements only the IOCTLs defined in the generic Enet Statistics API. There are no additional CPSW-specific IOCTLs.

The CPSW host port module provides additional IOCTL commands than those supported by the generci Enet Host Port API set.

CPSW host port clocks:

• CPSW_CPPI_CLK - CPSW main clock.

Compile-time configuration:

• ENET_CFG_CPSW_HOSTPORT_TRAFFIC_SHAPING - Traffic shaping (rate limit) support.
