218e99
218e99
Currently macvtap based macvlan device is working in promiscuous
218e99
mode, we want to implement mac-programming over macvtap through
218e99
Libvirt for better performance.
218e99
218e99
Design:
218e99
 QEMU notifies Libvirt when rx-filter config is changed in guest,
218e99
 then Libvirt query the rx-filter information by a monitor command,
218e99
 and sync the change to macvtap device. Related rx-filter config
218e99
 of the nic contains main mac, rx-mode items and vlan table.
218e99
218e99
This patch adds a QMP event to notify management of rx-filter change,
218e99
and adds a monitor command for management to query rx-filter
218e99
information.
218e99
218e99
Test:
218e99
 If we repeatedly add/remove vlan, and change macaddr of vlan
218e99
 interfaces in guest by a loop script.
218e99
218e99
Result:
218e99
 The events will flood the QMP client(management), management takes
218e99
 too much resource to process the events.
218e99
218e99
 Event_throttle API (set rate to 1 ms) can avoid the events to flood
218e99
 QMP client, but it could cause an unexpected delay (~1ms), guests
218e99
 guests normally expect rx-filter updates immediately.
218e99
218e99
 So we use a flag for each nic to avoid events flooding, the event
218e99
 is emitted once until the query command is executed. The flag
218e99
 implementation could not introduce unexpected delay.
218e99
218e99
There maybe exist an uncontrollable delay if we let Libvirt do the
218e99
real change, guests normally expect rx-filter updates immediately.
218e99
But it's another separate issue, we can investigate it when the
218e99
work in Libvirt side is done.
218e99
218e99
Michael S. Tsirkin: tweaked to enable events on start
218e99
Michael S. Tsirkin: fixed not to crash when no id
218e99
Michael S. Tsirkin: fold in patch:
218e99
   "additional fixes for mac-programming feature"
218e99
Amos Kong: always notify QMP client if mactable is changed
218e99
Amos Kong: return NULL list if no net client supports rx-filter query
