> This changes the message_age_timer calculation to use the BPDU's max age as
> opposed to the local bridge's max age.  This is in accordance with section
> 8.6.2.3.2 Step 2 of the 802.1D-1998 sprecification.
> 
> With the current implementation, when running with very large bridge
> diameters, convergance will not always occur even if a root bridge is 
> configured to have a longer max age.
> 
> Tested successfully on bridge diameters of ~200.
