Subject: [Crypto/chcr] calculating tx_channel_id as per the max number of channels
Date:   Fri, 13 Dec 2019 17:08:52 +0530
Message-Id: <1576237132-15580-1-git-send-email-ayush.sawal@chelsio.com>
Sender: linux-crypto-owner@vger.kernel.org
Precedence: bulk

chcr driver was not using the number of channels from lld and
assuming that there are always two channels available. With following
patch chcr will use number of channel as passed by cxgb4.
