If anyone has any objections, please let me know. ------------------ From: Malcolm Priestley commit aa209eef3ce8419ff2926c2fa944dfbfb5afbacb upstream. Hi, This patch fixes a bug with driver failing to negotiate a connection. The bug was traced to commit 203e4615ee9d9fa8d3506b9d0ef30095e4d5bc90 staging: vt6656: removed custom definitions of Ethernet packet types In that patch, definitions in include/linux/if_ether.h replaced ones in tether.h which had both big and little endian definitions. include/linux/if_ether.h only refers to big endian values, cpu_to_be16 should be used for the correct endian architectures.
