Interesting.  I'm currently using the aacraid driver from 2.4.21-ac4 and
it has the following defines section:


#define AAC_NUM_FIB     578
//#define AAC_NUM_IO_FIB   512
#define AAC_NUM_IO_FIB     100

//#define AAC_MAX_TARGET   (16)
#define AAC_MAX_LUN     (8)

This is still causing problems with timeouts (with write cache off) and
will crash with write cache on...
