If the request sending fails, it should not be updated.\n\nThis patch fix the above bug by roll back updates when the sending\nfails.\n\nFixes: 463e748964f57 (\"net/hns3: support mailbox\")\nCc: stable@dpdk.org\n\nSigned-off-by: Chengwen Feng <fengchengwen@huawei.com>\nSigned-off-by: Min Hu (Connor) <humin29@huawei.com>\n---\n drivers/net/hns3/hns3_mbx.c | 1 +\n 1 file changed, 1 insertion(+)", "diff": "diff --git a/drivers/net/hns3/hns3_mbx.c b/drivers/net/hns3/hns3_mbx.c\nindex ad0b4e6..3ba65f1 100644\n--- a/drivers/net/hns3/hns3_mbx.c\n+++ b/drivers/net/hns3/hns3_mbx.c\n@@ -142,6 +142,7 @@ hns3_send_mbx_msg(struct hns3_hw *hw, uint16_t code, uint16_t subcode,\n \t\thw->mbx_resp.head++;\n \t\tret = hns3_cmd_send(hw, &desc, 1);\n \t\tif (ret) {\n+\t\t\thw->mbx_resp.head--;\n \t\t\trte_spinlock_unlock(&hw->mbx_resp.lock);\n \t\t\thns3_err(hw, \"VF failed(=%d) to send mbx message to PF\",\n \t\t\t\t ret);\n", "prefixes": [ "07/10" ] }
