If this means that the "children" macvlans can't communicate with their "parent" interface as though they were all attached to the same virtual ethernet segment, I think that is a reasonable limitation. On other networking equipment I've used, the moment "sub-interfaces" are created, their parent interface can't be used for any communications, only for setting link related parameters e.g. for ethernet interfaces, speed and duplex etc. > > I've seen one panic during testing this that I still need > to track down, but it generally does what is advertised. > I've tested VEPA operation with the hairpin support > added to the bridge driver by Anna Fischer. > > My current plan is to submit this for inclusion in 2.6.33 > when people are happy with it and I tracked down any > remaining bugs, and possibly to do the communication with > the lower device one release later. > > Arnd <>< > > --- > > Arnd Bergmann (3): > macvlan: implement VEPA and private mode > macvlan: export macvlan mode through netlink > iplink: add macvlan options for bridge mode > > Eric Biederman (1): > macvlan: Reflect macvlan packets meant for other macvlan devices > > linux/drivers/net/macvlan.c | 170 +++++++++++++++++++++++++++++++++----- > linux/include/linux/if_link.h | 15 +++ > 2 files changed, 161 insertions(+), 24 deletions(-) > > iproute2/include/linux/if_link.h | 15 +++ > iproute2/ip/Makefile | 3 +- > iproute2/ip/iplink_macvlan.c | 93 ++++++++++++++++++ > 3 files changed, 110 insertions(+), 1 deletions(-) > create mode 100644 ip/iplink_macvlan.c > -- > To unsubscribe from this list: send the line "unsubscribe netdev" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html _______________________________________________ Bridge mailing list Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/bridge
