4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Thomas Egerer <hakke_...@gmx.de> commit 32b6170ca59ccf07d0e394561e54b2cd9726038c upstream. The ESP algorithms using CBC mode require echainiv. Hence INET*_ESP have to select CRYPTO_ECHAINIV in order to work properly. This solves the issues caused by a misconfiguration as described in [1]. The original approach, patching crypto/Kconfig was turned down by Herbert Xu [2].
