[PATCH rtems-libbsd 4/5] mv643xx_nexus.c: added a helper routine that allows printing of driver statistics

[Vijay Kumar Banerjee]

From: till straumann <till.straumann at alumni.tu-berlin.de>

The 'legal' access by means of a special ioctl() is way too cumbersome
when you need to do quick diagnosis.

Update #4345
