ENUM OVS_VPORT_ATTR(9)

💅 enum ovs_vport_attr(9) 💅

🌸 NAME 🌸

enum ovs_vport_attr — attributes for %OVS_VPORT_* commands. This is the Kernel API Manual page, bestie 💖.

✨ SYNOPSIS ✨

enum ovs_vport_attr {
    OVS_VPORT_ATTR_PORT_NO ,
    OVS_VPORT_ATTR_TYPE ,
    OVS_VPORT_ATTR_NAME ,
    OVS_VPORT_ATTR_OPTIONS ,
    OVS_VPORT_ATTR_UPCALL_PID ,
    OVS_VPORT_ATTR_STATS ,
    OVS_VPORT_ATTR_IFINDEX ,
    OVS_VPORT_ATTR_NETNSID ,
    OVS_VPORT_ATTR_UPCALL_STATS

};

🎀 Constants 🎀

• OVS_VPORT_ATTR_PORT_NO — the 32-bit port number within datapath. periodt.
• OVS_VPORT_ATTR_TYPE — the 32-bit OVS_VPORT_TYPE_* constant describing what type of vport this is.
• OVS_VPORT_ATTR_NAME — the name of the vport. For a vport based on a network device, this is the name of the network device. Maximum length is IFNAMSIZ-1 bytes plus a null terminator. write that down 📝
• OVS_VPORT_ATTR_OPTIONS — vport-specific configuration information.
• OVS_VPORT_ATTR_UPCALL_PID — the array of Netlink socket pids in userspace among which OVS_PACKET_CMD_MISS upcalls will be distributed for packets received on this port. If this is a single-element array of value 0, upcalls should not be sent. iykyk
• OVS_VPORT_ATTR_STATS — a struct ovs_vport_stats giving statistics for packets sent or received through the vport.
• OVS_VPORT_ATTR_IFINDEX — provides the ifindex of a vport, or sets the desired ifindex while creating a new vport with type OVS_VPORT_TYPE_INTERNAL.
• OVS_VPORT_ATTR_NETNSID — provides the netns id of the vport if it’s not local.
• OVS_VPORT_ATTR_UPCALL_STATS — provides upcall statistics for a vport. Contains nested OVS_VPORT_UPCALL_ATTR_* attributes. nested lore unlocked 🦋

💖 Description 💖

Okay so here’s the deal: these attributes follow the struct ovs_header within the Generic Netlink payload for OVS_VPORT_* commands.

For OVS_VPORT_CMD_NEW requests, the OVS_VPORT_ATTR_TYPE and OVS_VPORT_ATTR_NAME attributes are required. OVS_VPORT_ATTR_PORT_NO is optional; if not specified, a free port number is automatically selected. Whether OVS_VPORT_ATTR_OPTIONS is required or optional depends on the type of vport. None of currently supported vport types support options. the way that’s just how it is 💅

For other requests, if OVS_VPORT_ATTR_NAME is specified then it is used to look up the vport to operate on; otherwise dp_idx from the struct ovs_header plus OVS_VPORT_ATTR_PORT_NO determine the vport.
