Public bug reported:
Configuring an 802.3ad bond doesn't appear to work correctly. The following
entry in /etc/network/interfaces should configure an 802.3ad bond between
interfaces eth2 and eth3:
#auto bond0
iface bond0 inet static
address 10.191.62.2
netmask 255.255.255.0
broadcast 10.191.62.255
bond-slaves eth2 eth3
bond-primary eth2 eth3
bond-mode 802.3ad
bond-lacp_rate fast
bond-miimon 100
However, after booting the system, we have:
# ifconfig -a
bond0 Link encap:Ethernet HWaddr 00:1b:21:b7:21:ea

I can ping 10.191.62.2 after making the above changes. So, either I am
configuring /etc/network/interfaces incorrectly or ifupdown/ifenslave is
doing the wrong thing.
Note also the number of dropped packages on bond0. Why should I see any
dropped packages on the bond0 interface?
