ht/vht action frames will be sent to AP from station to notify change of its ht/vht opmode(max bandwidth, smps mode or nss) modified values. Currently these valuse used by driver/firmware for rate control algorithm. This patch introduces NL80211_CMD_STA_OPMODE_CHANGED command to notify those modified/current supported values(max bandwidth, smps mode, max nss) to userspace application. This will be useful for the application like steering, which closely monitoring station's capability changes. Since the application has taken these values during station association.
