	* kern/uipc_mbuf.c: The RTEMS version of the m_copyback is changing
	the m_len value of the mbuf.  I looked into the source from another
	BSD system and the mbuf length is not changed inside this function.
	The m_copyback function is only being used in the net/rtsock.c file.
	So I think this problem is only visable under certain routing table
	conditions.
