Subject: [PATCH 03/13] net/cnxk: fix later skip to include mbuf priv
Date: Tue, 11 Oct 2022 17:31:25 +0530 [thread overview]
Message-ID: <20221011120135.45846-3-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20221011120135.45846-1-ndabilpuram@marvell.com>
Fix later skip to include mbuf priv data as mbuf->buf_addr
is populated based on calculation including per-mbuf priv area.
Fixes: 706eeae60757 ("net/cnxk: add multi-segment Rx for CN10K")
