Hi,

I have the same thing :

# mii-tool -v bond0
bond0: 10 Mbit, half duplex, link ok
   product info: vendor 00:01:00, model 0 rev 4
   basic mode:   10 Mbit, half duplex
   basic status: link ok
   capabilities:
   advertising:

It's "mii-tool" getting confused. What matters are the bonded interface 
speed, not the speed of bond0 displayed by mii-tool.

Look at the speed of your physical interface and that will be the speed 
of bond0.

# ethtool eth0
Settings for eth0:
         Supported ports: [ FIBRE ]
         Supported link modes:   1000baseT/Full

         Speed: 1000Mb/s
         Duplex: Full
         Port: FIBRE
         PHYAD: 2
         Transceiver: internal
