From a31a1dbdf5e1ff46d04f50fea02e83453b84652c Mon Sep 17 00:00:00 2001 From: John Daley Date: Tue, 8 Mar 2016 10:49:07 -0800 Subject: [PATCH 12/22] 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 --- drivers/net/enic/base/enic_vnic_wq.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/net/enic/base/enic_vnic_wq.h b/drivers/net/enic/base/enic_vnic_wq.h index e3ea574..b019109 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_ */ -- 1.9.1
