Subject: [dpdk-dev] [PATCH v1] net/iavf: fix cannot release mbufs issue
Date: Wed, 11 Nov 2020 11:06:51 +0800 [thread overview]
Message-ID: <20201111030651.15535-1-ting.xu@intel.com> (raw)
In the function _iavf_rx_queue_release_mbufs_vec to release rx mbufs,
rxq->rxrearm_nb is given the value of rx descriptor number at last.
However, since the process to release and allocate mbufs lacks the
initialization of rxrearm_nb, if we try to release mbufs next time, it
will return without releasing directly. In this patch, rxrearm_nb is
initialized to be zero in rx queue reset.
Fixes: 319c421f3890 ("net/avf: enable SSE Rx Tx")
