Subject: [PATCH V3 11/25] smartpqi: add host level stream detection enable
Date: Thu, 10 Dec 2020 14:35:24 -0600 [thread overview]
Message-ID: <160763252438.26927.15696823365021360866.stgit@brunhilda> (raw)
In-Reply-To: <160763241302.26927.17487238067261230799.stgit@brunhilda>
* Allow R5/R6 stream detection to be disabled/enabled.
using sysfs entry enable_stream_detection.
Example usage:
lsscsi
[2:2:0:0] storage Adaptec 3258P-32i /e 0010
