Massive verbose output at system log

[stolz@ya.com]

I have realized my /var/log/messages file is ~150M. It's
filled up thousands of lines like:
wlan0: WMM queue=2 aci=0 acm=0 aifs=2 cWmin=7 cWmax=1023 burst=20
wlan0: WMM queue=3 aci=1 acm=0 aifs=7 cWmin=15 cWmax=1023 burst=0

Is there any reason for such a massive verbose output from
wpa_supplicant? Is it something to worry about? Or it can be
considered normal.
