Subject: [PATCH] crypto: qat - Set max request size
Date: Fri, 05 Jun 2015 15:51:18 -0700 [thread overview]
Message-ID: <20150605225118.4911.47264.stgit@tstruk-mobl1> (raw)
The device doensn't support the default value and will change it to 256, which
will cause performace degradation for biger packets.
Add an explicit write to set it to 1024.
