Date: Tue Dec 12 2017 - 08:24:13 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: LEROY Christophe <christophe.leroy@xxxxxx>

commit fbb22137c4d9bab536958b152d096fb3f98020ea upstream.

sg_link_tbl_len shall be used instead of cryptlen, otherwise
SECs which perform HW CICV verification will fail.
