SVN rev 199679 on 2009-11-22 21:45:55Z by yongari
Reduce status block size DMAed by controller. bge(4) uses single
Tx/Rx/Rx return ring such that large part of status block was not
used at all. All bge(4) controllers except BCM5700 AX/BX has a
feature to control the size of status block. So use minimum status
block size allowed in controller. This reduces number of DMAed
status block size to 32 bytes from 80 bytes.
