I'm noticing a very large buffer miss rate on a GEIP controller (very
similar to a VIP2-50 with a Gigabit port adapter):

Public buffer pools:
Small buffers, 104 bytes (total 25, permanent 25):
     25 in free list (20 min, 60 max allowed)
     2 hits, 0 misses, 0 trims, 0 created
     0 failures (0 no memory)
Middle buffers, 600 bytes (total 15, permanent 15):
     15 in free list (10 min, 30 max allowed)
     8 hits, 0 misses, 0 trims, 0 created
     0 failures (0 no memory)
Big buffers, 1524 bytes (total 100, permanent 5):
     6 in free list (5 min, 10 max allowed)
     2547640 hits, 861395 misses, 2231939 trims, 2232034 created
     104574 failures (0 no memory)
VeryBig buffers, 4520 bytes (total 148, permanent 50):
     148 in free list (40 min, 300 max allowed)
     104574 hits, 112 misses, 21 trims, 119 created
     0 failures (0 no memory)
Large buffers, 5024 bytes (total 0, permanent 0):
     0 in free list (0 min, 5 max allowed)
     0 hits, 0 misses, 0 trims, 0 created
     0 failures (0 no memory)
Huge buffers, 18024 bytes (total 1, permanent 1):
     1 in free list (0 min, 2 max allowed)
     0 hits, 0 misses, 0 trims, 0 created
     0 failures (0 no memory)

The buffer settings are very different from the RSP, and I think that's not
only because of particle pool memory allocation that the VIP does. How to
set buffer parameters for VIP/GEIP ?
