[OpenWrt-Devel] [PATCH] hostapd netifd wmm configuration for speedup wifi.

[N.Leiten]

Speed up wifi up to 2 times in Access Point mode. On rt5350 platfrom I
got speed up from 35-40Mbit to 70-80Mbit, on ar71xx I got improvement
from 45Mbit to 100Mbit with this parameters set in hostapd.conf. It
seems that hostapd expects not only 'wmm_enabled=1' key but also
parameters for WMM.
