Subject: [ 097/135] staging: vt6656: [BUG] - Failed connection, incorrect endian.
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Malcolm Priestley <tvboxspy@...il.com>
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.
