Subject: hostapd: correctly handle macfile uci option
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=541fbfbb9e7fac2700359c76509d4844ea8607ff;p=openwrt%2Fstaging%2Frmilecki.git

hostapd: correctly handle macfile uci option

Make hostapd.sh correctly handle the macfile uci option.

Such option specifies the macfile name to pass into the
hostapd configuration file. Moreover, if a maclist option
has been specified, copy the macfile before appending new
entries.
