Hi All, I need to write a driver for the High Speed serial Interface of IXP425 platform using the Intel provided Access library. The HSS access library stores the packet in a MBUF (defined in Intel access lib) format. Do i need to write a Packet driver /character driver for this ?. I should be able to identify the packet (HDLC frame) boundaries of the packets coming into the High Speed Serial interface. I need to provide API's to the user space applications to read and write data to the HSSI. Has anyone written software driver using the Intel access library components?
