Subject: [PATCH v2 1/5] examples/l3fwd: fix port group mask generation
Date: Fri, 2 Sep 2022 14:48:29 +0530 [thread overview]
Message-ID: <20220902091833.9074-1-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20220829094442.3422-1-pbhagavatula@marvell.com>
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Fix port group mask generation in altivec, vec_any_eq returns
0 or 1 while port_groupx4 expects comparison mask result.
Fixes: 2193b7467f7a ("examples/l3fwd: optimize packet processing on powerpc")
