TIPC needs to have its endianess issues fixed. Unfortunately, the format of a subscriber message is passed in directly from user space, so requiring this message to be in network byte order breaks user space ABI. Revert this change until such time as we can determine how to do this in a backwards compatible manner. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.
