When PF\nreceived this command, it may reset the VF and send a notification\nbefore resetting. If this notification is read by the timed task alarm,\nTask request queue will lost notification. This patch Mark vf_reset,\npend_msg flag just as task request queue has received notification in\ntask alarm.\n\nFixes: 864a800d70 (\"net/i40e: remove VF interrupt handler\")\nFixes: ee653bd800 (\"net/i40e: determine number of queues per VF at run time\")\nCc: stable@dpdk.org\n\nSigned-off-by: Zhu Tao <taox.zhu@intel.com>\n---\n drivers/net/i40e/i40e_ethdev_vf.c | 4 ++++\n 1 file changed, 4 insertions(+)", "diff": "diff --git a/drivers/net/i40e/i40e_ethdev_vf.c b/drivers/net/i40e/i40e_ethdev_vf.c\nindex 5be32b069..3b9740c08 100644\n--- a/drivers/net/i40e/i40e_ethdev_vf.c\n+++ b/drivers/net/i40e/i40e_ethdev_vf.c\n@@ -1332,6 +1332,10 @@ i40evf_handle_pf_event(struct rte_eth_dev *dev, uint8_t *msg,\n \t\tPMD_DRV_LOG(DEBUG, \"VIRTCHNL_EVENT_RESET_IMPENDING event\");\n \t\t_rte_eth_dev_callback_process(dev, RTE_ETH_EVENT_INTR_RESET,\n \t\t\t\t\t NULL);\n+\t\tif (!vf->vf_reset) {\n+\t\t\tvf->vf_reset = true;\n+\t\t\tvf->pend_msg |= PFMSG_RESET_IMPENDING;\n+\t\t}\n \t\tbreak;\n \tcase VIRTCHNL_EVENT_LINK_CHANGE:\n \t\tPMD_DRV_LOG(DEBUG, \"VIRTCHNL_EVENT_LINK_CHANGE event\");\n", "prefixes": [ "v2" ] }
