From 289f81258e03067d032f9c157c91cd1fad7b31c5 Mon Sep 17 00:00:00 2001 From: Yunsheng Lin Date: Fri, 28 Jun 2019 19:50:17 +0800 Subject: [PATCH] net: hns3: remove RXD_VLD check in hns3_handle_bdinfo The HNS3_RXD_VLD_B bit has already been checked in hns3_add_frag or hns3_handle_rx_bd before calling hns3_handle_bdinfo, so when hns3_handle_bdinfo is called, the HNS3_RXD_VLD_B bit is always set, which makes the checking in hns3_handle_bdinfo unnecessary. This patch removes the RXD_VLD_B checking in hns3_handle_bdinfo. Signed-off-by: Yunsheng Lin Signed-off-by: Peng Li Signed-off-by: Huazhong Tan Signed-off-by: David S.
