^^^^^^^^^
Not related to this this patch but this confused me initially. UINT_MAX
would be more readable.
The other unrelated question I had about this function was:
402 /* search for a winner using edca params */
403 for (i = 0; i < IEEE80211_NUM_ACS; ++i) {
^^^^^^^^^^^^^^^^^
IEEE80211_NUM_ACS is 4.
404 int queued;
405
406 edca = &wvif->edca_params[i];
407 queued = wfx_tx_queue_get_num_queued(&wvif->wdev->tx_queue[i],
408 tx_allowed_mask);
409 if (!queued)
410 continue;
411 *total += queued;
412 score = ((edca->aifs + edca->cw_min) << 16) +
413 ((edca->cw_max - edca->cw_min) *
414 (get_random_int() & 0xFFFF));
415 if (score < best && (winner < 0 || i != 3)) {
^^^^^^
Why do we not want winner to be 3? It's unrelated to the patch but
there should be a comment next to that code probably.
416 best = score;
417 winner = i;
418 }
419 }
