[ixp1200] number of rings

[Shyamal Pandya]

The resource managerand ixconfig  code are the place to look for how the 
rings are alllocated. I believe the maximum is 32 rings for each queue 
group.
For the simple count application only two of the microengines are used, one 
fr egress and one for egress. I don't remember the ring assignments but the 
code and the comments in the resource manager should be of good help here.
Of course there is one ring per port from which the egress microblock reads 
packets.
