We currently have a request to turn on CONFIG_MACVTAP as this can provide
performance inprovements for KVM.
There are two allied configuration options MACVLAN and MACVTAP. Both are
currently experimental.
config MACVLAN
tristate "MAC-VLAN support (EXPERIMENTAL)"
depends on EXPERIMENTAL
---help---
This allows one to create virtual interfaces that map packets to
or from specific MAC addresses to a particular interface.
Macvlan devices can be added using the "ip" command from the
iproute2 package starting with the iproute2-2.6.23 release:
"ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
To compile this driver as a module, choose M here: the module
will be called macvlan.
config MACVTAP
tristate "MAC-VLAN based tap driver (EXPERIMENTAL)"
depends on MACVLAN
help
This adds a specialized tap character device driver that is based
on the MAC-VLAN network interface, called macvtap. A macvtap device
can be added in the same way as a macvlan device, using 'type
macvlan', and then be accessed through the tap user space interface.
To compile this driver as a module, choose M here: the module
will be called macvtap.
So far we do have MACVLAN turned on:
debian.master/config/config.common.ubuntu:CONFIG_MACVLAN=m
debian.master/config/config.common.ubuntu:# CONFIG_MACVTAP is not set
As they seem to be opt-in devices and seem to be self contained it
seems safe to enable these.
Proposing for Oneiric.
