And this data region exists\nas an array. As a result, some complicated feature commands,\nlike mailbox response, link change event, close promisc mode,\nreset request and update pvid state, have to use magic number\nto set them. This isn't good for maintenance of driver. So\nthis patch refactors these messages by extracting an\nhns3_pf_to_vf_msg structure.\n\nFixes: 463e748964f5 (\"net/hns3: support mailbox\")\nCc: stable@dpdk.org\n\nSigned-off-by: Dengdui Huang <huangdengdui@huawei.com>\nSigned-off-by: Jie Hai <haijie1@huawei.com>\n---\n drivers/net/hns3/hns3_mbx.c | 38 ++++++++++++++++++-------------------\n drivers/net/hns3/hns3_mbx.h | 25 +++++++++++++++++++++++-\n 2 files changed, 43 insertions(+), 20 deletions(-)", "diff": "diff --git a/drivers/net/hns3/hns3_mbx.c b/drivers/net/hns3/hns3_mbx.c\nindex ad5ec555b39e..c90f5d59ba21 100644\n--- a/drivers/net/hns3/hns3_mbx.c\n+++ b/drivers/net/hns3/hns3_mbx.c\n@@ -192,17 +192,17 @@ static void\n hns3vf_handle_link_change_event(struct hns3_hw *hw,\n \t\t\t\tstruct hns3_mbx_pf_to_vf_cmd *req)\n {\n+\tstruct hns3_mbx_link_status *link_info =\n+\t\t(struct hns3_mbx_link_status *)req->msg.msg_data;\n \tuint8_t link_status, link_duplex;\n-\tuint16_t *msg_q = req->msg;\n \tuint8_t support_push_lsc;\n \tuint32_t link_speed;\n \n-\tmemcpy(&link_speed, &msg_q[2], sizeof(link_speed));\n-\tlink_status = rte_le_to_cpu_16(msg_q[1]);\n-\tlink_duplex = (uint8_t)rte_le_to_cpu_16(msg_q[4]);\n-\thns3vf_update_link_status(hw, link_status, link_speed,\n-\t\t\t\t link_duplex);\n-\tsupport_push_lsc = (*(uint8_t *)&msg_q[5]) & 1u;\n+\tlink_status = (uint8_t)rte_le_to_cpu_16(link_info->link_status);\n+\tlink_speed = rte_le_to_cpu_32(link_info->speed);\n+\tlink_duplex = (uint8_t)rte_le_to_cpu_16(link_info->duplex);\n+\thns3vf_update_link_status(hw, link_status, link_speed, link_duplex);\n+\tsupport_push_lsc = (link_info->flag) & 1u;\n \thns3vf_update_push_lsc_cap(hw, support_push_lsc);\n }\n \n@@ -211,7 +211,6 @@ hns3_handle_asserting_reset(struct hns3_hw *hw,\n \t\t\t struct hns3_mbx_pf_to_vf_cmd *req)\n {\n \tenum hns3_reset_level reset_level;\n-\tuint16_t *msg_q = req->msg;\n \n \t/*\n \t * PF has asserted reset hence VF should go in pending\n@@ -219,7 +218,7 @@ hns3_handle_asserting_reset(struct hns3_hw *hw,\n \t * has been completely reset.
