[dpdk-dev] [PATCH] doc/qat: fix table of kernel drivers

[Fiona Trahe <fiona.trahe@intel.com>]

Added missing line informing which kernel driver can
be used for device DH895xcc for compression service.
Moved service columns to start of table for better visibility
and to prepare for future asymmetric crypto service.

Fixes: e2e35849ea78 ("compress/qat: add compression on DH895x")
Cc: stable@dpdk.org

+The first 3 columns indicate the service:
+
+* S = Symmetric crypto service (via cryptodev API)
+* A = Asymmetric crypto service  (via cryptodev API)
+* C = Compression service (via compressdev API)
 
 The ``Driver`` column indicates either the Linux kernel version in which
 support for this device was introduced or a driver available on Intel's 01.org
-website. There are both linux and 01.org kernel drivers available for some
+website. There are both linux in-tree and 01.org kernel drivers available for some
 devices. p = release pending.
 
 If you are running on a kernel which includes a driver for your device, see
