4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yi Zhao <yi.z...@windriver.com>
commit 83e2d0587ae859aae75fd9d246c409b10a6bd137 upstream.
It doesn't support to run 32bit 'ip' to set xfrm objdect on 64bit host.
But the return value is unknown for user program:
ip xfrm policy list
RTNETLINK answers: Unknown error 524
Replace ENOTSUPP with EOPNOTSUPP:
ip xfrm policy list
RTNETLINK answers: Operation not supported
