Subject: [dpdk-stable] [PATCH] net/mvpp2: fix non-EAL thread support
Date: Tue, 16 Jun 2020 11:47:00 +0200 [thread overview]
Message-ID: <20200616094700.31749-1-david.marchand@redhat.com> (raw)
Caught by code inspection, for a non-EAL thread identified with
rte_lcore_id() == LCORE_ID_ANY, the code currently arbitrarily uses
lcore 0 while there is no guarantee this lcore is used.
Fixes: 3588aaa68eab ("net/mrvl: fix HIF objects allocation")
Cc: stable@dpdk.org
Signed-off-by: David Marchand <david.marchand@redhat.com>
