Some devices have 31 TFD queues. Don't enable it yet since there are still issues with it, but at least prepare the code for it. There was a bug in the read pointer assignment, fix that. Also, move the inline functions to iwl-scd.h which is the right place. Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
