Subject: hostapd: add ucode support, use ucode for the main ubus object
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e56c5f7b276a17f4c9b9321e1e6fbef0bf8ca6c6;p=openwrt%2Fstaging%2Fthess.git

hostapd: add ucode support, use ucode for the main ubus object

This implements vastly improved dynamic configuration reload support.
It can handle configuration changes on individual wifi interfaces, as well
as adding/removing interfaces.
