Subject: qmgr for ixp4xx

Hi

As I am trying to use my HSSs as 4E1, I find that the FIFOs for each
HDLC should be 1 word wide and not 4 words wide. I think that this
finally means that when accessing the queues, I have to do the
following modification.

diff -urN linux-2.6.26.7_hssorig/include/asm-arm/arch-ixp4xx/qmgr.h

 static inline int qmgr_get_stat1(unsigned int queue)

Is it correct?

Thanks
