From: Wei Fang <[email protected]> Add two interfaces to manage entries in the VLAN filter table:
ntmp_vft_update_entry(): Update the configuration element data of the specified VLAN filter entry based on the given VLAN ID. It uses the exact key access method to locate the entry. ntmp_vft_delete_entry(): Delete the VLAN filter entry corresponding to the specified VLAN ID. It also uses the exact key access method to identify the target entry. In addition, introduce struct vft_req_qd to describe the request data buffer format for Query and Delete actions of the VLAN filter table, which contains a common request data header and a VLAN access key.
