From: John Daley Date: Tue, 8 Mar 2016 18:49:07 +0000 (-0800) Subject: enic: fix last packet not being sent X-Git-Tag: spdx-start~7417 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=aba31298526865f5db99eaa54b63eb39dc95b74f;p=dpdk.git enic: fix last packet not being sent The last packet of the tx burst function array was not being emitted until the subsequent call. The nic descriptor index was being set to the current tx descriptor instead of one past the descriptor as required by the nic. Fixes: d739ba4c6abf ("enic: improve Tx packet rate") Signed-off-by: John Daley --- diff --git a/drivers/net/enic/base/enic_vnic_wq.h b/drivers/net/enic/base/enic_vnic_wq.h index e3ea5742a2..b019109352 100644 --- a/drivers/net/enic/base/enic_vnic_wq.h +++ b/drivers/net/enic/base/enic_vnic_wq.h @@ -69,11 +69,11 @@ static inline void enic_vnic_post_wq(struct vnic_wq *wq, buf->wr_id = wrid; buf = buf->next; - if (cq_entry) - enic_vnic_post_wq_index(wq); + wq->ring.desc_avail -= desc_skip_cnt; wq->to_use = buf; - wq->ring.desc_avail -= desc_skip_cnt; + if (cq_entry) + enic_vnic_post_wq_index(wq); } #endif /* _ENIC_VNIC_WQ_H_ */
