net/sched: fq_pie: re-factor fix for fq_pie endless loop
the patch that fixed an endless loop in_fq_pie_init() was not considering that 65535 is a valid class id. The correct bugfix for this infinite loop is to change 'idx' to become an u32, like Colin proposed in the past [1]. Fix this as follows: - restore 65536 as maximum possible values of 'flows_cnt' - use u32 'idx' when iterating on 'q->flows' - fix the TDC selftest This reverts commit bb2f930d.
