Subject: set mtu from bridge also on vif interface
|
||
|
|
References: bug#625394
|
||
|
|
|
||
|
|
Apply mtu size from bridge interface also in vif interface.
|
||
|
|
This depends on a kernel change which allows arbitrary mtu sizes until
|
||
|
|
the frontend driver has connected to the backend driver. Without this
|
||
|
|
kernel change, the vif mtu size will be limited to 1500 with this change
|
||
|
|
to the vif-bridge script.
