Classes
struct	oa_tc6_frame_buffer
	Stores an Ethernet frame along with metadata needed for parsing. The MAC driver or the user application will receive and submit frames for transmission in this format. More...
struct	oa_tc6_flags
	Stores the status flags which are provided as part of the footer during data transfers. These flags will be latched by the driver and can be cleared by the user when reading. More...
struct	oa_tc6_desc
	Holds the frame buffers and the communication descriptor for the OA TC6 driver. More...
struct	oa_tc6_init_param
	Holds the initialization parameters for the OA TC6 driver. More...
