Subject: [PATCH v3 03/15] net/dpaa2: warn user in case of high nb desc
Date: Mon, 3 Jan 2022 15:31:17 +0530 [thread overview]
Message-ID: <20220103100129.23965-4-nipun.gupta@nxp.com> (raw)
In-Reply-To: <20220103100129.23965-1-nipun.gupta@nxp.com>
From: Rohit Raj <rohit.raj@nxp.com>
Added warning message if application is configuring nb_desc
more than supported by PEB memory suggesting user to configure
HW descriptors in normal memory rather than in faster PEB
memory.
Signed-off-by: Rohit Raj <rohit.raj@nxp.com>
