Detailed Description

eSPI out-of-band transaction packet format

• For Tx packet, eSPI driver client shall specify the OOB payload data and its length in bytes.
• For Rx packet, eSPI driver client shall indicate the maximum number of bytes that can receive, while the eSPI driver should update the length field with the actual data received/available.
