Hi Augusto, many thanks for your interesting email.
Do you think some delay is needed between writing and reading the
registers?

It's nice to have a more-or-less working skystar2 driver also for
2.6B, but, IMHO, we should reduce the pace trying to improve it.
We all know that it has a lot of bugs, and we should try to locate
these first.

My proposal:
Let's start with a debug on a very low level, first:
Let's start with open_whole_bandwidth() first, and forget about
hw-filters: that way, we can check the upper layer, and - if it
isn't the upper layer's fault - we will have to check the irq rou-
tines.
Scan will be a good test program for this, as it is requesting quite
a few pids/filters at the same time.

If this turns out to be fine one day, we can add hw-filters (0-5, and
the additional 0-31), one day.

I also propose a new debug value: debug=2 should mean the debug
we already have, the filter stuff dprintk's should be changed to some-
thing like iprintk, with a debug value of 1.

What do you think?

Wolfgang
