                              guint32 *out_to);

Retrieve one of the entries of the “ingress_priority_map” or “egress_priority_map” properties of this setting.

Parameters

setting	the NMSettingVlan
map	the type of priority map
idx	the zero-based index of the ingress/egress priority map entry
out_from	on return the value of the priority map's 'from' item.	[out][allow-none]

nm_setting_vlan_add_priority ()

gboolean
nm_setting_vlan_add_priority (NMSettingVlan *setting,

                              guint32 to);

Adds a priority mapping to the “ingress_priority_map” or “egress_priority_map” properties of the setting. If from is already in the given priority map, this function will overwrite the existing entry with the new to .

If map is NM_VLAN_INGRESS_MAP then from is the incoming 802.1q VLAN Priority Code Point (PCP) value, and to is the Linux SKB priority value.

If map is NM_VLAN_EGRESS_MAP then from is the Linux SKB priority value and to is the outgoing 802.1q VLAN Priority Code Point (PCP) value.

Parameters

setting	the NMSettingVlan
map	the type of priority map
from	the priority to map to `to`
to	the priority to map `from` to

Returns

TRUE.

                                 guint32 idx);

Removes the priority map at index idx from the “ingress_priority_map” or “egress_priority_map” properties.

Parameters

setting	the NMSettingVlan
map	the type of priority map
idx	the zero-based index of the priority map to remove

nm_setting_vlan_remove_priority_by_value ()

gboolean
nm_setting_vlan_remove_priority_by_value
                               (NMSettingVlan *setting,
                                NMVlanPriorityMap map,
                                guint32 from,
                                guint32 to);

Removes the priority map form :to from the “ingress_priority_map” or “egress_priority_map” (according to map argument) properties.

Parameters

setting	the NMSettingVlan
map	the type of priority map
from	the priority to map to `to`
to	the priority to map `from` to

Returns

TRUE if the priority mapping was found and removed; FALSE if it was not.

nm_setting_vlan_remove_priority_str_by_value ()

gboolean

Removes the priority map str from the “ingress_priority_map” or “egress_priority_map” (according to map argument) properties.

Parameters

setting	the NMSettingVlan
map	the type of priority map
str	the string which contains a priority map, like "3:7"

nm_setting_vlan_clear_priorities ()

void
nm_setting_vlan_clear_priorities (NMSettingVlan *setting,
                                  NMVlanPriorityMap map);

Clear all the entries from “ingress_priority_map” or “egress_priority_map” properties.

Parameters

setting	the NMSettingVlan
map	the type of priority map

nm_setting_vlan_add_priority_str ()

gboolean
nm_setting_vlan_add_priority_str (NMSettingVlan *setting,
                                  NMVlanPriorityMap map,
                                  const char *str);

Adds a priority map entry into either the “ingress_priority_map” or the “egress_priority_map” properties. The priority map maps the Linux SKB priorities to 802.1p priorities.

Parameters

setting	the NMSettingVlan
map	the type of priority map
str	the string which contains a priority map, like "3:7"

Returns

TRUE if the entry was successfully added to the list, or it overwrote the old value, FALSE if str is not a valid mapping.

Types and Values

#define NM_SETTING_VLAN_INGRESS_PRIORITY_MAP "ingress-priority-map"

NM_SETTING_VLAN_EGRESS_PRIORITY_MAP

#define NM_SETTING_VLAN_EGRESS_PRIORITY_MAP  "egress-priority-map"

enum NMVlanPriorityMap

A selector for traffic priority maps; these map Linux SKB priorities to 802.1p priorities used in VLANs.

Members

NM_VLAN_INGRESS_MAP	map for incoming data
NM_VLAN_EGRESS_MAP	map for outgoing data

enum NMVlanFlags

NMVlanFlags values control the behavior of the VLAN interface.

Members

NM_VLAN_FLAG_REORDER_HEADERS	indicates that this interface should reorder outgoing packet headers to look more like a non-VLAN Ethernet interface
NM_VLAN_FLAG_GVRP	indicates that this interface should use GVRP to register itself with its switch
NM_VLAN_FLAG_LOOSE_BINDING	indicates that this interface's operating state is tied to the underlying network interface but other details (like routing) are not.
NM_VLAN_FLAG_MVRP	indicates that this interface should use MVRP to register itself with its switch

NM_VLAN_FLAGS_ALL
