Subject: [dpdk-dev] [PATCH v1] net/mlx5: fix rxq object allocation with MPRQ
Date: Wed, 4 Nov 2020 07:55:20 +0000 [thread overview]
Message-ID: <20201104075520.23508-1-ophirmu@nvidia.com> (raw)
The space for extra buffer pointers used by MPRQ routines was not
allocated in Rx queue object creation structure causing memory
corruption.
The fix allocates the extra memory for the pointers in case MPRQ is
engaged.
Fixes: f6dcff4788a1 ("net/mlx5: configure Rx queue for buffer split")
