Configure the counter. Driver uses the command whose opcode is\n HNS3_OPC_FD_AD_OP, now we extend one bit to hold the high bit of\n counter-id in the command format.\n2. Query the statistic information of the counter. Driver uses the command\n whose opcode is HNS3_OPC_FD_COUNTER_OP, now the command already support\n 16-bit counter-id.\n\nSigned-off-by: Chengwen Feng <fengchengwen@huawei.com>\nSigned-off-by: Wei Hu (Xavier) <xavier.huwei@huawei.com>\n---\n drivers/net/hns3/hns3_fdir.c | 5 +++++\n 1 file changed, 5 insertions(+)", "diff": "diff --git a/drivers/net/hns3/hns3_fdir.c b/drivers/net/hns3/hns3_fdir.c\nindex 6ab439d06..5c3dd05f2 100644\n--- a/drivers/net/hns3/hns3_fdir.c\n+++ b/drivers/net/hns3/hns3_fdir.c\n@@ -41,6 +41,8 @@\n #define HNS3_FD_AD_WR_RULE_ID_B\t0\n #define HNS3_FD_AD_RULE_ID_S\t\t1\n #define HNS3_FD_AD_RULE_ID_M\t\tGENMASK(13, 1)\n+#define HNS3_FD_AD_COUNTER_HIGH_BIT 7\n+#define HNS3_FD_AD_COUNTER_HIGH_BIT_B 26\n \n enum HNS3_PORT_TYPE {\n \tHOST_PORT,\n@@ -424,6 +426,9 @@ static int hns3_fd_ad_config(struct hns3_hw *hw, int loc,\n \t\t action->write_rule_id_to_bd);\n \thns3_set_field(ad_data, HNS3_FD_AD_RULE_ID_M, HNS3_FD_AD_RULE_ID_S,\n \t\t action->rule_id);\n+\t/* set extend bit if counter_id is in [128 ~ 255] */\n+\tif (action->counter_id & BIT(HNS3_FD_AD_COUNTER_HIGH_BIT))\n+\t\thns3_set_bit(ad_data, HNS3_FD_AD_COUNTER_HIGH_BIT_B, 1);\n \tad_data <<= HNS3_FD_AD_DATA_S;\n \thns3_set_bit(ad_data, HNS3_FD_AD_DROP_B, action->drop_packet);\n \thns3_set_bit(ad_data, HNS3_FD_AD_DIRECT_QID_B,\n", "prefixes": [ "06/11" ] }
