qtnfmac: get rid of QTNF_STATE_AP_START flag
Browse files Browse the repository at this point in the history
QTNF_STATE_AP_START usage is redundant and imposes additional state
synchronization maintenance. We may as well leave state checking
to network card and upper layers (cfg80211, nl80211 and userspace).
