Subject: [PATCH 4.14 17/38] crypto: chelsio - select CRYPTO_GF128MUL

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

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

From: Arnd Bergmann <arnd@...db.de>

commit d042566d8c704e1ecec370300545d4a409222e39 upstream.

Without the gf128mul library support, we can run into a link
error:

drivers/crypto/chelsio/chcr_algo.o: In function `chcr_update_tweak':
chcr_algo.c:(.text+0x7e0): undefined reference to `gf128mul_x8_ble'

This adds a Kconfig select statement for it, next to the ones we
already have.

Fixes: b8fd1f4170e7 ("crypto: chcr - Add ctr mode and process large sg entries for cipher")
