Problems using bonding with vlan

[Shmulik Hen <shmulik.hen@intel.com>]

Hi,

Consider the following scenario:
# insmod <some-base-driver>
# insmod 8021q
# insmod bonding mode=X miimon=Y
# vconfig add bond0 10
# ifenslave bond0 eth0 eth1 ...
# ifconfig bond0.10 a.b.c.d

Now try to run ping - no traffic. Arp tables on all clients show that 
the server has hardware address 00:00:00:00:00:00 !

The only way for it to work is:
# ifenslave bond0 eth0 eth1 ...
# vconfig add bond0 10
# ifconfig bond0.10 a.b.c.d

But that's probably not the way things happen during boot via the 
network scripts.

I think we should add to the 8021q module the ability to listen to 
netdev events and to set it's hardware address whenever the 
underlying device changes it own, instead of just during the VLAN 
interface creation.

Comments ?
