Subject: [dpdk-dev] [PATCH] common/octeotx2: add support for C0 silicon version
Date: Mon, 13 Jan 2020 10:33:02 +0530 [thread overview]
Message-ID: <20200113050303.3511-1-ndabilpuram@marvell.com> (raw)
Avoid using PCI subsystem device id for SoC revision
identification and just use PCI revision id to support C0 silicon.
This patch also reduces SQB threshold to 70% to have
sufficient buffer before we overflow SQ.
