Subject: hostapd: check for banned client on association event
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b6320a63a20c323aa56330fbb8a34deae8d1b298;p=openwrt%2Fstaging%2Fnbd.git

hostapd: check for banned client on association event

When using FullMAC drivers (e.g. brcmfmac) we don't get mgmt frames so
check for banned client in probe request handler won't ever be used.
Since cfg80211 provides us info about STA associating let's put a check
there.
