Hi, All:

My RWAIP MC7455 has been allocated an IP address from wireless network and this IP address is registered in Linux host (ipconfig and DHCP are succeeded). While it has some issue on sending/receiving data packets.  I found the following info

This patch adds support for "raw IP" framing for QMI devices,
changing the netdev from an ethernet device to an ARPHRD_NONE
p-t-p device when "raw IP" framing is enabled.

Is it meaning that data packets shall be send to MC7455 with IP header + no MAC address , and there is no ARP needed? Which type of socket shall be generated to RAW IP interface, i.e. socket(PF_INET, SOCK_RAW, htons(IPPROTO_RAW))?
