[Bug 889423] Re: 802.3ad bonding not configured correctly

I do not see any dropped packets.

In syslog I have a lot of these:
[10292.612017] bonding: bond0: Warning: Found an uninitialized port

Attaching my /proc/net/bonding/bond0 & ifconfig outputs

** Description changed:

  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
+   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:

  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?
