This patch fixes a noisy warning triggered by -Wenum-compare |main.c:1390:31: warning: comparison between ‘enum nl80211_ac’ | and ‘enum ar9170_txq’ [-Wenum-compare] | BUILD_BUG_ON(NL80211_NUM_ACS > __AR9170_NUM_TXQ); | ^ | [...] This is a little bit unfortunate, since the number of queues (hence NL80211_NUM_ACS) is a constant based on the IEEE 802.11 (much like IEEE80211_NUM_ACS) and __AR9170_NUM_TXQ is more or less defined by the AR9170 hardware.
