This happens if\nother VF drivers (like DPDK) send a message through the driver's\nmailbox (aka virtchannel) interface, but the message is not\nsupported by the i40e pf driver, such as CONFIG_PROMISCUOUS_MODE.\n\nThis patch changes the num_invalid_msgs in struct i40e_vf to record\nthe continuous invalid msgs, and it will be reset when a valid msg\nis received.\n\nSigned-off-by: Jingjing Wu <jingjing.wu@intel.com>\nSigned-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com>\nChange-ID: Iaec42fd3dcdd281476b3518be23261dd46fc3718\n---\n drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c | 2 ++\n drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.h | 3 ++-\n 2 files changed, 4 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c\nindex 3ed8b98..d84b727 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c\n@@ -1105,6 +1105,8 @@ static int i40e_vc_send_msg_to_vf(struct i40e_vf *vf, u32 v_opcode,\n \t\t}\n \t} else {\n \t\tvf->num_valid_msgs++;\n+\t\t/* reset the invalid counter, if a valid message is received. */\n+\t\tvf->num_invalid_msgs = 0;\n \t}\n \n \taq_ret = i40e_aq_send_msg_to_vf(hw, abs_vf_id,\tv_opcode, v_retval,\ndiff --git a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.h b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.h\nindex 7fe94e8..da44995 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.h\n+++ b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.h\n@@ -96,7 +96,8 @@ struct i40e_vf {\n \n \tu8 num_queue_pairs;\t/* num of qps assigned to VF vsis */\n \tu64 num_mdd_events;\t/* num of mdd events detected */\n-\tu64 num_invalid_msgs;\t/* num of malformed or invalid msgs detected */\n+\t/* num of continuous malformed or invalid msgs detected */\n+\tu64 num_invalid_msgs;\n \tu64 num_valid_msgs;\t/* num of valid msgs detected */\n \n \tunsigned long vf_caps;\t/* vf's adv. capabilities */\n", "prefixes": [ "next", "S16", "10/15" ] }
